Changes for vile 6.0 (released Tue Jun 18, 1996)

(pgf)    960618
    + no longer use non-standard RCS extensions to generate revlist.
      this is slower, but it works always.  (makefile.in)

    + change makefile targets "tar" and "shar" to "tarball" and
      "sharball". (makefile.in)

    + add "const" to tempnam() args to satisfy reported problem with
      DEC C -- apparently there is already a prototype in scope for
      tempnam().  (vms2unix.c)

    + documented (years late :-) the "save-keyboard-macro" command,
      which will copy the keyboard macro to a named register. (vile.hlp)

    + allow arg. to "load-register" to force a full-line style load.
      this allows
          1 use-register e load-register "#endif"
      to be used to duplicate a 'yy' of "#endif".  previously you
      could not get the full-line effect, i.e. it worked like 'yW'.
      (line.c)

(tom)    960612 (zg)
    + modify configure script, putting test for socket, nsl libraries after
      X-libraries, to avoid duplication (configure.in)

    + modify cd/pwd logic to recover better when the current and parent
      directories aren't readable by the current process (path.c, random.c).

(tom)    960527 (zf)
    + added "--enable-echo" option to configure.in

    + applied Andy Harper's correction for VMS 'tempnam()'.

    + added VC_AC_PREREQ macro to allow conditional generation of the
      configure script, according to whether my patches for autoconf have
      been applied.  Added local copy of new autoconf macros as well
      (configure.in, aclocal.m4).

    + reordered autoconf macros (aclocal.m4)

    + redefine AC_MSG_CHECKING, AC_CHECKING so that they log the same info
      to config.log (aclocal.m4).

    + removed VC_SIZE_T because recent autoconf checks stdlib.h
      (aclocal.m4, configure.in)

    + removed VC_TEST_GETPGRP macro (aclocal.m4, estruct.h, configure.in)

    + removed VC_SETPGRP macro (aclocal.m4, proto.h, configure.in, main.c)

    + added aliases for Sf, Sb termcap capabilities (AF, AB) for ANSI
      termcap descriptions.

(tom)    960522 (ze)
    + corrected a couple of lengths for strncpy0 calls (file.c)

    + modify handling of toggle-buffer-list so that giving a parameter
      overrides the default pop/unpop, and toggles the listing of invisible
      buffers instead (buffer.c)

(pgf)    960516 (zd)
    + clarifications regarding file/command/shell completion (vile.hlp).

    + modified quote() routine to allow input of decimal values -- now
      entering ^VNNN, ^V0NNN, or ^VxNN will insert the character with
      that decimal, octal, or hex vale.  (255 max).  entering fewer
      than 3 digits will enter the value, and the terminating character
      will be "ungotten" and then re-consumed as usual.  feature
      requested by user, implementation inspired by vim.  (insert.c,
      vile.hlp)

    + added digraphs.rc, a set of :map! commands to aid the insertion
      of ISO 8859/1 8-bit characters.  the ^Kcc form of the maps (and
      their exact values) is borrowed from vim.  (digraphs.rc,
      makefile.in, vile.hlp, makefile.djg)

    + the [Standard Input] buffer is now marked "read-only" rather
      than "view" to match other piped-to buffers.  (all clients of
      set_rdonly() affected, since argument was added.)

    + removed disclaimer from help file regarding x! and w!.

    + added -R option to set "readonly" mode, put -v back to setting
      "view" mode as it used to, updated man page to reflect all this.
      (vile.1, main.c)

    + the initial response to a ":e" prompt is defaulted to the first
      command line argument to vile.  (file.c, main.c)

(kev)    960417 (zc)
    + configure.in, configure:  Changed configure.in so that configure
      will run cleanly and create something useful in a Sparc / Solaris
      / X11R6 environment.  Regenerated configure.  Also fixed a few of
      the autoconf warnings for configure.in.

    + makefile.in (X_EXTRA_LIBS, X_PRE_LIBS): Removed these makefile
      variables.

(tom)    960416 (zb)
    + further corrected 'shell_complete()' to test and adjust for leading
      "!", and use this to also simplify call from 'cmd_complete()'
      (bind.c, input.c).

    + prevent 'do_lines_in_region()' from processing the nominal end of a
      full-line region, since that is off-by-one to accommodate width
      requirements; this fixes ":.,.+3>>>" (region.c).

(kev)    960416 (za)
    + basic.c (setcursor): Permit the mouse to set the cursor when
      doing an "op" command.  Prevent MK from becoming corrupted if
      call too set_curwp() caused a window change.

    + filec.c (mlreply_file): Use Tom's filename completion stuff
      on shell commands for things like ":e !gunzip -c /usr/doc/<TAB>".

    + input.c (shell_complete): Fixed an off-by-one/beginning-of-buffer
      bug.  [The variable "base" should never be less than zero after
      the termination of the "for" loop.]

(tom)    960415 (z)
    + show read-only mode in status line (display.c)

    + refined/corrected VMS pathname translations, to better handle root
      directory, and ^X-e command (file.c, filec.c, glob.c, path.c,
      vms2unix.c).

    + implemented filename-completion in shell commands (bind.c, filec.c,
      input.c)

    + modified filename-completion to recognize environment variables
      (filec.c).

    + change token-expansion from ':' to '&' for VMS and MS-DOS (estruct.h,
      input.c, main.c).

    + implement error-finder for CSet C/C++ (finderr.c)

(tom)    960410 (y)
    + modified TERM struct so that no function-pointers should be null.
      Inactive functions are assigned from the null device's TERM struct.
      This provides better type-checking, as well as getting rid of
      no-effect compiler warnings.

    + restored <dir.h> include for TurboC (random.c)

    + adjusted ifdef's to allow changes to 'imdying()' to compile on
      MS-DOS and OS/2 (file.c).

(pgf)    960329 (x)
    + new modes:  "readonly", which prevents writing a buffer out, and
      "readonly-on-readonly", which sets this mode if the buffer is not
      writable according to the OS.  setting the latter causes vile to
      mimic vi's default behavior.  it is off by default.  "vile -v",
      invoking as "view", and reading from a pipe all now set
      "readonly" mode rather than "view" mode.  (modetbl, main.c,
      file.c, vile.hlp, vile.1)

    + better (?) help on using '/' as a path delimter on PC operating
      systems. (vile.hlp)

    + new command, "set-unix-mode", as a complement to "set-dos-mode".
      this capability was there before as "1:set-dos-mode", but it sure
      was hard to explain to people.  (cmdtbl, vile.hlp, file.c)

(jrs)    960328 (w)
    + estruct.h: Make TERM "optional" members "mandatory" and protect
      references to all optionally implemented members with null
      checks.
    + ansi.c, at386.c, borland.c, dg10.c, dumbterm.c, hp110.c, hp150.c,
      ibmpc.c, ntconio.c, st520.c, tcap.c, termio.c, tipc.c, vmsvt.c,
      vt52.c, x11.c, z309.c, z_ibmpc.c: Remove all TERM-related optional
      ifdefs and replace all stub functions with null function pointers.
    + borland.c: Convert function defintions to ANSI C and make most
      functions static.
    + estruct.h: Add new optional window title method to TERM and
      enable it for WIN32.
    + buffer.c: Optionally set window title based on buffer name.
    + dirstuff.h: Use <direct.h> instead of <dirent.h> with Visual C++.
    + estruct.h: Remove unnecessary ifdefs around undefs.
    + file.c: Compile a working version of imdying on all platforms.
    + history.c: We want to use our own isgraph so undef the OS version.
    + npopen.c: Do all I/O redirections while keyboard is closed.
    + ntconio.c: Make most functions static, make the insertion
      cursor code match the expected optional interface, implement
      the TERM title method, unsucessfully try to catch abrupt
      exits and do something about them, die gracefully if console
      I/O fails.
    + path.c: Remove unused code to downcase the path in is_msdos_drive.
    + random.c: Change a bunch of compiler ifdefs to a single include
      of dirstuff.h which already handles all of the special cases.
      Add a judicious downcasing on non-caseless MS-DOS-like systems
      like DJGPP to compensate for the above-mentioned change to
      is_msdos_drive.
    + termio.c: Don't put WIN32 typeahead code here since it is
      already dispatched via TERM methods.
    + README.PC: Various documentation fixes.

(tom)    960323 (v)
    + removed tmp.c and OPT_MAP_MEMORY

(tom)    960317 (u)
    + added "compile-error-expressions" to allow macros to force the [Error
      Expressions] buffer to be created; otherwise it would only be created
      on the first use of "find-next-error" (finderr.c).

    + modified predefined error-expressions to remove unnecessary ':';
      making them a little more general.  This makes the error finder
      slower, however (finderr.c).

    + modified RegStrChr2 to eliminate unnecessary 3rd parameter, making it
      faster.  Use 'const' where possible in this file (regexp.c).

(tom)    960308 (t)
    + correction to test for 'PC':  linker on HP/UX allows read from
      non-existent location during configuration (configure.in).

    + corrected special cases in word-wrap, by refining 'blanks_on_line()',
      and use of 'n' in 'wordwrap()' (input.c, word.c).

(pgf)    960307 (s)
    + added b_lines_on_disk element to BUFFER struct, to get back
      "count from bottom" functionality in finderr. (file.c, finderr.c,
      estruct.h)

    + patch from jim hourihan to support "Cpp" keywork in vile-c-filt,
      to allow colorizing all cpp lines at once, rather than listing
      keywords individually. (c-filt.c, vile.hlp)

(tom)    960303 (r)
    + corrected sign-extension of characters (map.c)

    + added termcap capability for "@7" (Key_end)

    + modified treatment of 'PC' in termcap driver; it should be extern
      since it is "owned" by 'tputs()' (tcap.c).

    + modified termcap driver to treat \200 specially in the key mapping
      i.e., add a mapping with the corresponding \0 (tcap.c)

(pgf)    960228 (q)
    + when notabinsert was active, autoindent accounting was being
      done incorrectly, causing excess whitespace to be left if
      you entered a '#' in cmode.  (insert.c)

    + removed OPT_BSD_FILOCK, since it hasn't ever been used, and
      the placeholders it was maintaining were incomplete, to say
      the least.  (main.c, file.c, estruct.h)

    + eliminate old screen files, that haven't been touched in a
      while.  (at386.c, dg10.c, hp110.c, hp150.c, st520.c, vt52.c,
      x11simp.c, z309.c, z_ibmpc.c)

    + eliminate old SCREEN defines and ifdefs.  (ansi.c, display.c,
      edef.h, epath.h, estruct.h, file.c, fileio.c, ibmpc.c, makefile.in,
      spawn.c, termio.c, win31drv.c)


(tom)  96022? (p)
    + use 'const' where applicable (lots of places :-)

    + generate externs for CMDFUNC objects in nefunc.h (mktbls.c, all
      makefiles, and C-files that had declared externs of these).

    + modified 'pathname[]' to separate out the 'exec_pathname' variable,
      to make the remaining pathname[] data const.

(tom)  960224 (o)
    + correct logic of 'is_absolute_pathname()'; for VMS we need to ensure
      that the pathname contains brackets or colons (path.c).

(tom)  960220 (n)
    + modify autoconf script to allow "--with-screen=ncurses" to link
      with terminfo support (configure.in).

    + modify 'zotwp()' to switch to the most recently-used buffer instead
      of the first one found, fixing behavior under noautobuffer mode
      (buffer.c).

(tom)  960212 (m)
    + modify autoconf script to add $X_PRE_LIBS and $X_EXTRA_LIBS in the
      X configuration tests (configure.in).

    + corrected potential null-pointer reference for $abufname (eval.c).

(tom)  960204 (l)
    + modify 'pathcat()' so that if the 'leaf' given is an absolute
      pathname, then we'll ignore the 'path' (usually an implied
      directory), to handle case in finderr when a full pathname is parsed
      (path.c).

    + modify logic of find-next-error so that multiple distinct matches
      on the same line will show up in the message-line (finderr.c).

    + remove P macro (and ANSI_PROTO) from several modules (c-filt.c,
      manfilt.c, mktbls.c).

    + change 'int' to 'long' in places where we cast to/from pointer
      (region.c, x11.c).

    + added TTflush to tcapkclose so that xterm-mouse is reset properly
      when spawning subshell (tcap.c).

    + moved X_CFLAGS to CPPFLAGS definition so that lint works for xvile
      (makefile.in).

(tom)  960118 (k)
    + convert function definitions to ANSI form (55 c&h files affected),
      so that K&R form is no longer used.  Removed macro ANSI_VARARGS, and
      reduced ACTUAL_SIG_ARGS definition.  Compiled with VAX-C, TurboC,
      WatCom 10.0a, gcc 2.5.8, gcc 2.7.2 (Linux, SunOS, Solaris, HP/UX 9),
      CLIX, IRIX, SCO, UnixWare 1.2.  Also used 'unproto' to compile SunOS
      and HP/UX.  Used ansi2knr for initial changes (i.e., finding places
      that used K&R syntax), but this patch does not use ansi2knr.

      This is not fully ANSI -- vile uses a number of Posix functions that
      aren't recognized in strict ANSI modes by a number of compilers.
      It does require that the compiler recognize prototypes and stdarg.h

(jrs)  960108 (j)
    + path.c (curr_dir_on_drive) [SYS_WINNT]: Translate drive argument
      from a drive letter (e.g. 'A' or 'a') to a drive number (e.g. 1)
      since this is what _getdcwd expects.
      (lengthen_path): Predicate curr_dir_on_drive call on OPT_MSDOS_PATH
      instead of listing individual systems so that e.g. this code is
      also compiled in on SYS_WINNT.  Check for curr_dir_on_drive
      failure and handle that case by assuming the current directory
      on a non-existent drive is the root directory.

(pgf)  960107 (i)
    + change order of TTkclose and TTclose in ttclean.  i think this
      will give us back old behavior wrt terminals that have TI/TE
      sequences.  we want to finish any screen-oriented i/o before
      calling ttkclose.  (termio.c)

    + removed okay_to_ask param from make_bp() and unqname(), since
      it is now unused.  removed return value from unqname().  (exec.c,
      file.c, proto.h)

    + fixed unqname to continue trying wider and wider suffixes until
      a unique name is found.  it will still loop, but only after a
      very large number of buffernames has been tried.  uses base-36
      index on end of filename. (file.c, proto.h)

    + added %r to dofmt -- takes two args, uses the first as a radix
      with which to print the second.  (display.c)

    + bp->b_bname is now null-terminated (again?).  it's really much
      cleaner this way.  NBUFN has changed
      from 20 to 21, to make room for the null.  eliminated get_bname()
      routine.  (buffer.c, display.c, edef.h, estruct.h, eval.c,
      exec.c, file.c, finderr.c, input.c, main.c, modes.c, proto.h,
      spawn.c, tags.c, tmp.c)

    + added a chgd_hilite() side-effect function, which causes
      a call to attrib_matches() when any of "magic", "ignorecase",
      or "visual-matches" is changed.

    + split up the "level" arg, which was overloaded to mean
      two things, into two separate args, one which says it's a
      global value we're changing, and the other which says we're
      just testing whether we can change it.  (estruct.h, modes.c)

    + guard against null gregexp in attrib_matches() -- possible
      if pattern failed to compile, making pat[0] non-null, but
      gregexp null.  (search.c)

    + fix ifdefs to make it easier to test dos pipes under unix.  get
      rid of duplicate close in dos readPipe, pointed out by jrs.  (the
      second close is out in filterregion()).  (npopen.c, spawn.c,
      proto.h)

(tom)    960105 (h)
    + corrected inadvertant K&R substitution in APP_S macro, moved
      bsd-lint expressions to avoid shadowing (finderr.c).

(pgf)    960103 (g)
    + prevent characters following ^A, ^X and # prefixes from being
      subject to remapping.  (input.c, vile.hlp)

    + small change to "find matching indent" macros in vile.hlp, to
      make them work when they encounter non-empty blank lines. (vile.hlp)

    + tweak watcom makefile to use "protected mode" compiler.
      selectable as $(CC), in case this breaks 10.x compiles.
      (makefile.wat)

    + fix for identifiers starting with '_', from sean ahern. (c-filt.c)


(tom)    960103 (f)
    + corrected reference to char beyond regular expression in regexp
      via 'lregexp()' function (regexp.c).

    + corrected 'free()' of null pointer in finderr.c, and retested with
      compile & lint logs, covering most most of the regular expressions in
      that module (finderr.c)

(jrs)    951231 (e)
    + configure.in (AC_HAVE_FUNCS): Move it after library checks
      (so we can test for functions in auxiliary libraries) and
      add checks for the functions tparm and tparam.

    + djhandl.c (ctrl_c_count, was_ctrl_c_hit): Declare it as unsigned
      long instead of u_long for DJGPP v2.

    + estruct.h [CC_DJGPP]: Define HAVE_UNISTD_H to eliminate some
      not declared warnings with DJGPP v2.
      (OPT_COLOR) [DISP_TERMCAP]: Don't conditionalize it based on
      Linux.

    + gppconio.c: Suppress the entire file under DJGPP v2 because the
      bugs it was supposed to fix are fixed.

    + makefile.djg (vile rule): Don't let stubedit globbing=no
      failure prevent a sucessful build for DJGPP v2 which doesn't
      seem to support it.

    + os2vio.c (PRETTIER_SCROLL): Don't define it.
      (vio_scroll): Base conditional scrolling code on
      OPT_PRETTIER_SCROLL instead of PRETTIER_SCROLL.

    + proto.h (was_ctrl_c_hit): Adjust prototype to match new
      definition.

    + tcap.c (tparm) [HAVE_TPARM]: Declare it.
      (tparam) [HAVE_TPARAM]: Declare it.
      (show_ansi_colors) [HAVE_TPARM]: Use tparm instead of tparam.

    + version.c (getversion) [CC_DJGPP]: Discriminate DJGPP v2 from
      the previous version.

(jrs)    951224 (d)
    + file.c (getfile2bp): Never consult the user about duplicate
      buffer names if `warn-rename' isn't on.

    + filec.c (headers): Don't supress inclusion of dirstuff.h
      on OS/2 since it doesn't hurt anything.
      (fillMyBuff) [SYS_OS2]: Only down-case filenames read from
      a directory if the drive they are on is not case-preserving.

    + main.c (global_val_init): Initialize `warn-rename' so that
      it defaults to the existing behavior.

    + modetbl (warn-rename): New option.

    + ntconio.c [SUPPORT_BROKEN_SCROLLING]: Rip out the ifdefs and
      compile it unconditionally since the case it applies to now
      no longer affects the efficiency of the most common case.

    + path.c (headers) [SYS_OS2]: Include os2.h.
      (is_case_preserving, case_correct_path) [SYS_OS2]: New functions.

    + version.c (getversion) [CC_CSETPP]: Discriminate VisualAge C++
      from C Set ++.

    + vile.hlp (warn-rename, warn-reread): Document them.

(tom)    951223 (c)
    + rewrote error-finder to support runtime-modifiable error regular
      expressions (finderr.c, edef.h)

    + added b_rmbuff member to BUFFER struct to notify error-finder when
      its buffer is removed; the b_upbuff member handles the modify
      events (estruct.h, buffer.c).

    + use macros b_set_obsolete/b_clr_obsolete (buffer.c, display.c)

    + use RBRACK/LBRACK definitions throughout (filec.c, vms2unix.c)

    + corrected missing initialization of CHARCELL link in extend_line()
      that occasionally broke vile-manfilt (manfilt.c).

(tom)    951217 (b)
    + lint (basic.c bind.c dumbterm.c exec.c insert.c line.c main.c map.c
      oneliner.c patchlev.h path.c random.c search.c select.c tags.c
      x11.c), including correcting error return within gotoeol(), and also
      testing error return from bclear() in pregion(), and
      attributeregion() in clear_match_attrs().

    + corrected ifdef'd logic from vile 5.5a with new function 'ins_mode()'
      replacing logic that's only used in mouse-code (display.c)

(jrs)    951216 (a)
    + bind.c (fill_partial): Use StrNcmp of length 1 instead of
      char equality to inherit case-insensitive comparision
      when extending completions as far as possible.  This is
      so that if we have `bind.c' and `BIND.OBJ' we will complete
      up to `bind.' if OPT_CASELESS is enabled.

    + file.c (fileread): Explicitly check for additional command
      line input so that `e! RET' doesn't prompt for more input.
      In that case, default to the filename of the current buffer
      and optionally prompt for replacement based on the new option
      `warn-reread'.

    + filec.c (mlreply_file): Supress prompting to reread the
      current buffer based on the new variable `warn-reread'.
      This is for people who like `e! RET' to assume they know
      what they're doing.

    + main.c (global_val_init): Initialize `warn-reread' so that
      it defaults to the existing behavior.

    + makefile.wnt (LDFLAGS): New variable to control debugging
      and the logo.
      (vile.exe, mktbls.exe): Use it.

    + modetbl (warn-reread): New option.

    + ntconio.c (ntscroll): Remove cRest variable and its
      initialization since the default is what we want anyway.
      Ensure that rectangles are described by their last row
      or column, not its sucessor.  Narrow the amount of
      backfilled scrolled areas by noting that the bug is the
      failure to backfill the non-overlapped portion of a scroll.

Changes for vile 5.6 (released Thu Dec 14, 1995)
(pgf)
    + allow "position-window" to be used from macros, e.g.
      "position-window bottom".  giving it an arg now reframes to
      that line from top or bottom, e.g. "11 position-window top".
      (cmdtbl, eval.c, vile.hlp, window.c)

(pgf)    951212 (f)
    + writing a region (e.g. ":.,$w foo") when the ends of the
      region did not fit on the screen would cause "BUG: updpos...".
      now fixed, by ensuring that moves are always flagged correctly.
      (btw, this was hidden by anything else that set a w_flag bit,
      like "ruler" mode.) (exec.c)

    + fixed propagation of null character when highlighting string
      literals that span lines.  (c-filt.c)

    + fixed description of label syntax (vile.hlp)

(tom)    951209 (e)
    + implemented "next-tag" function, bound to ^A-^], which steps through
      alternate tags definitions for the last tag value (cmdtbl, tags.c).

    + ifdef'd out code that causes vile to die when it receives an EOF
      (linux only, termios.c)

    + modified to allow trivial (one-match only) glob-expansion of items in
      'tags' mode so that ~/tags and $HOME/tags work (tags.c).

(pgf)    951209 (d)
    + take out call to wrapword() in newline(), which caused an
      extra newline in some wrapping cases.  the condition it was
      taking care of is now caught earlier on.  (insert.c)

(pgf)    951208 (c)
    + created separate .zip targets for watcom and djgpp builds, since
      i seem to have to switch back and forth all the time.  (makefile.in)

    + do_num_proc and do_rept_arg_proc would accept ^X or ^A prefixes
      followed by digits as further modifications to the argument
      count, so 2 ^X-2 wouldn't work as advertised.  now it does.
      (main.c)

    + fixed kbd_reply() so that starting a response with ^V now
      clears the existing response -- it used to append the
      quoted character instead.  (input.c)

    + correction for showmatch mode when the left fence is the first
      character in the buffer. (fences.c)

    + better explanation of difference between "wrapword" mode
      and newer "wrapmargin" mode.  (vile.hlp)

    + added fallback define of S_ISDIR in path.c.

(tom)    951205 (b)
    + corrected value of 'fname' in 'readin()' after calling 'ch_fname()';
      this may have been the original bp->b_fname value, which is
      reallocated when resolving a pathname (file.c).

    + modified to check for null pointer return from 'create_msgs()'
      (msgs.c)

(tom)    951203 (a)
    + corrected logic of 'line_height()' to get rid of unwanted wraparound
      on the last column of the screen when linewrap mode is set (display.c)

Changes for vile 5.5 (released Sun Nov 19, 1995)
(pgf)
    + added tags file format information to vile.hlp.

    + removed vmalloc.{c,obj} from makefile.{djgpp,wnt,blc}

    + prevent ^T from inserting spaces if "notabinsert" is set. (insert.c)

    + force two spaces after a ':' when reformatting paragraphs. (word.c)

    + mention screen resolution control on PC in man page. (vile.1)

    + trimmed trailing whitespace from vile.hlp.  where does that stuff
      come from, anyway?

    + fix forceblank() to consider lines containing whitespace to be
      blank.  (random.c)

    + call upmode() when resetting modeline format.  (eval.c)

    + vms C compiler complains about folded pre-processor lines.  sigh.
        (mktbls.c)

    + added two new macro accessible functions, &local and &global, which
      return the value of a vile setting.  for instance, "&global cmode"
      will give the global cmode setting (true or false) and "&local list"
      will give the local autoindent mode setting.  (modes.c, eval.c,
      modetbl, macros.doc, vile.hlp)

    + minor fixes for incremental searching: better tie-in with 'n' and
      'N' commands, and uses CR as search terminator.  (search.c,
      isearch.c, edef.h)  (from s.suresh)

    + eliminate vttidy(), since it had degenerated to a simple
      wrapper for ttclean().  call ttclean() directly in all cases.
      (spawn.c, termio.c, version.c, file.c, main.c, proto.h, display.c)

    + put TTkopen() call into ttunclean, so that keybad and xterm-mouse
      translation get turned back on after a suspend or shell escape.
      and then i removed it again.  the TI sequence for the linux
      console homes the cursor.  not a good thing just before a
      pressreturn().  but pressreturn() needs the termio stuff that
      ttunclean does.  so they have to remain separate.
      (termio.c, main.c)

    + introduced swbuffer_lfl() which takes lockfl as arg.  swbuffer() is
      a wrapper which calls swbuffer_lfl() with lockfl == TRUE (the old
      behavior).  this allows getting rid of the early readin() that was
      happening in bp2swbuffer() (due to the lack of a lockfl arg), which
      was in turn causing read hooks to run too early, before the buffer
      state (modes, name, etc.) was set up correctly.  (buffer.c, file.c,
      proto.h)

    + rearranged swbuffer_lfl to make sure it does the right thing
      with inactive buffers.  (buffer.c)

    + small addition to vile.hlp regarding where comments can appear
      in command files (i.e. probably only on lines by themselves)

    + i couldn't configure xvile on sunos 4.1.3 with X11R6 installed,
      because the test link against -lXt failed, due to missing -lSM
      and -lICE.  these have already been tested for and found, so i
      added $X_PRE_LIBS to the check for -lXt.  this seems to fix it
      and also seems benign.  is this right?  (configure.in, configure,
      makefile.in)

(tom)
    + corrected a bug in wrapmargin that caused it to split and alarm
      at the wrong point (insert.c, word.c).

    + corrected a bug in linewrap; when the user appended to the end of
      a line longer than the window, the beginning of the line was
      overwriting the modeline of the next window (display.c).

    + modified termcap color support to work with rxvt 2.12 (tcap.c).

    + rewrote logic for color mode-type to make it an enum-type, more
      general, and made the visual-matches mode an enum (modetbl, main.c,
      modes.c, search.c).  This makes name-completion work properly on
      enumerated types.

    + added 'default' enum value for termcap colors and added logic to
      reset colors to default, i.e., orig_colors on exit (modes.c, tcap.c).

    + modified color modes to be global, since we don't support per-window
      colors anymore (modetbl, display.c, main.c).

    + changed 'popup-choices' to a enum-type (modetbl, bind.c, main.c).

    + make the 'spal()' function a member of the TERM struct to eliminate
      unused/dummy functions, and to capture internal initialization
      of 'palstr' (lot of places).

    + corrected error in vile-manfilt that dumped core due to off-by-one
      in realloc threshold, and fixed a memory leak (manfilt.c)

    + added global mode 'resolve-links' to control whether vile resolves
      and caches directory names (modetbl, main.c, path.c).


Changes for vile 5.4 (released Thu Oct 19, 1995)

(jrs)
    + This revision provides improved support for Windows NT and
      Windows 95.  The screen performance is dramatically faster
      and a new completion mechanism is introduced which is
      neither purely case-sensitive like Unix nor purely
      case-insensitive like traditional MS-DOS.  This is used
      to cleanly support case-insensitive but case-preserving
      filesystems such as MS-DOS FAT with long filenames or
      native NTFS.

    + bind.c, proto.h: Add case insensitive flag to kbd_complete,
      skip_partial, show_partial, show_completions, scroll_completions,
      and fill_partial.  Take care to propgate case changes
      which occur during completion to the keyboard input area.

    + eval.c, modes.c: Change kbd_complete callers.

    + dirstuff.h, makefile.wnt: Repair crufty WIN32 port.

    + edef.h: Rename the operating system `windows/nt' as `win32'.

    + estruct.h: Rework compiler and system defines so that
      Visual C++ is detected and so that Borland C++ can be used
      to compile the WIN32 version.  Also undef some more common
      names like ABORT which pollute the namespace of many
      environments.

    + file.c: Make getfile2bp external so that it can be called from
      main.  Use the canonical name instead of the supplied name
      to form the buffer name for case-insensitive, case-preserving
      filesystems.  This change makes `:e readme RET' for a file
      whose real name is `README' have a buffer named `README'.

    + main.c: Use getfile2bp instead of make_bp so file specified
      on the command line behave more like found files; confer
      the above example.

    + filec.c, glob.c: Never lowercase WIN32 filenames and instead
      compare them case-insensitively.  Pass case-insensitive flag to
      kbd_complete on WIN32.

    + path.c: For WIN32 call the new function realpath from
      canonpath so that the preserved case of a filename is
      reconstructed even though a different case was used to
      access the file.

    + termio.c: For WIN32 add prototype for ntgetch and don't call
      kbhit.

    + version.c: Discriminate between Turbo C and Borland C++ to
      clarify and shorten the version string.  Add support for
      Visual C++.

    + makefile.blc: Yet another makefile for WIN32 (like makefile.wnt)
      which uses Borland C++ instead of Visual C++.

    + ntconio.c: Massive overhaul for performance, consistency,
      bug fixes and new features.  The driver is dramatically
      faster now because of reduced API transactions through
      batching and because of avoidance of inherently slow functions
      such as WriteConsole.  Correct a number of inconsistencies with
      the other MS-DOS-like drivers such as the use of bright
      white and clearing the screen upon exit.  Fix a number of
      bugs such a bad interaction between kbhit and getch and
      work around a bad bug in the Windows 95 implementation of the
      WIN32 Console API.  Enhance the driver to support all of the
      function and editing keys and some missing control-key
      combinations.

    + bind.c, filec.c: Temporarily disable case insensitive reply
      correction for now since it doesn't work reliably and it only
      provides a cosmetic advantage.

    + estruct.h: Add a new option OPT_UNC_PATH for systems
      which support Universal Naming Convention (UNC) pathnames.
      Enable for win32.  Turn on ellipsis and range globbing on
      win32.  Define new glob range negation characters (^ and !).

    + filec.c, glob.c, path.c: Change numerous conditionals specific
      to win32 to use the new OPT_CASELESS option.

    + glob.c: Extend globbing to handle OPT_CASELESS.  Fix bug which
      prevented ranges from working on any platform.  Implement
      range negation.

    + ntconio.c: Disable mouse support until the bugs are worked out.
      Don't allow non-keyboard events to cause type ahead check to
      loop forever.

    + dirstuff.h: Clean up crufty ifdefs and defines for win32
      directory operations.

    + path.c: Correct faulty mapping between _getdrive and curdrive.
      Rename realpath to case_correct_path and use it for OPT_CASELESS.
      Handle UNC pathnames correctly during canonicalization and
      case correction.  Fix bugs in case correction that showed up
      because of differences between Windows NT and Windows 95.
      Fix bug in internal name detection that prevented range globbing
      from working at the beginning of a pattern (e.g. `[a-z]*').
      Make pure system and share UNC pathnames (e.g. `\\system\share')
      always appear as directories so completion on them works.
      This works around a bug in the win32 file attribute semantics.
      Be sure not to add `\*.*' to a directory that ends with `\'
      in the the MSVC opendir replacement, add just `*.*' instead.
      Fix monster memory leaks in MSVC readdir replacement and change
      mechanism to allow multiple simultaneous open directories.

    + makefile.wnt: Suppress annoying compiler banner.

    + fileio.c: Work around another Microsoft bug and make ffsize
      work reliably on files remotely mounted from Windows 95 systems
      by using stdio instead of fstat.  Also use the default isready_c
      because WIN32 stdio is either MS (which is like traditional
      stdio) or Borland which is already handled.

    + main.c: Only make '~' a wildcard character on Unix since we only
      expand ~login on Unix.  This allows short filenames which contain
      tilde to be expanded properly (e.g. C:\PROGRA~1 => C:\Program Files)
      on WIN32.

    + makefile.in: Add the WIN32 Borland C makefile to the official
      distribution.

    + npopen.c: Handle WIN32 like MS-DOS, not like Unix so that
      command filtering works correctly without much effort.

    + ntconio.c: Re-enable mouse input and completely rewrite the
      mouse handling to use the generic selection code shared with
      X11.  This change fixes a number of WIN32 mouse bugs and saves
      about 100 lines of code.

    + path.c: Rewrite case_correct_path for WIN32 so that it correctly
      handles strings which grow on expansion such as those files
      which include any short-name components.

    + proto.h, select.c, x11.c: Compile the selection yanking code
      on WIN32 and add an argument which controls which register to
      yank into.  Change all callers.

    + spawn.c: Remove crufty inclusion of sys/stat that seems not
      to be needed on any platform.  Even if it is, it should be
      safe to include it unqualified as it is in other files.
      Change the default COMSPEC from cmd.exe to command.com on
      WIN32 since there is no cmd.exe on Windows 95 but there is
      a command.com on Windows NT.  In any case, COMSPEC is usually
      set.  Enable filterregion code on WIN32 since inout_popen
      now works.

(kev)
    + x11.c (x_preparse_args): Make sure that the scroll bar GC has
      the graphics exposures field set to false.  (The calls to XCopyArea
      using the scrollbar GC are from a pixmap which will always be
      copied in its entirety.

    + x11.c: Changed resources so that default colors will be various
      shades of gray.  This code is presently disabled.

    + x11.c (copy_paste): #if'd out the code which caused pasting at
      the beginning of a line to be put on the line above and pasting
      at the end of a line to be put on the line below.  Just define
      OLD_PASTE to be 1 if you want the old behavior back.

    + x11.c (x_expose_scrollbar): Renamed from x_expose_pane.

      (update_scrollbar_sizes): Set up an event handler for scrollbar
      expose events.

      (x_preparse_args): Removed call to set up expose event handler
      for panes.

      The above changes were made because popup menus (from other
      applications) could cover up the scrollbar and not redraw it
      properly (I don't really know why).

    + x11.c (curs_sb_v_double_arrow, curs_sb_up_arrow, curs_xterm
      curs_sb_down_arrow, curs_sb_left_arrow, curs_sb_right_arrow,
      curs_double_arrow, curs_watch): Moved these out of struct
      _text_win so that they are global.  This'll be handy for the day
      when someone gets up the courage to actually create multiple
      (top-level) X windows.  There's a lot of other stuff to be moved
      out, but this is a start.

      (slider_is_3D, scrollbargc_lt, scrollbargc_dk): New fields in
      struct _text_win.

      (alloc_shadows): New function which allocates pixels for light
      and dark shading for a 3-D look.

      (draw_thumb, update_thumb, x_expose_pane, x_preparse_args): Added
      new code for drawing 3-D scrollbars.

    + input.c (kbd_reply): Set reading_msg_line to FALSE _after_
      popping down the completions window in order to ensure that the
      buffer hook does not get run.  (It should not have been run when
      popping the buffer up either, so when it's popped down, the
      situtation should be the same prior being popped up.)

    + buffer.c (make_current, run_buffer_hook): Removed the message
      line check from make_current() and moved it to run_buffer_hook.
      We do not want to run the buffer hook if reading from the message
      line.  See below (I fixed this once before) for more information.

    + modetbl (SMOOTH_SCROLL): New boolean mode.

    + main.c (global_val_init): Initialize GMDSMOOTH_SCROLL value.
      Default is false so that it'll jump.

    + display.c (update, updupd): Added additional test to the "return
      early" code to enforce smooth scrolling if GMDSMOOTH_SCROLL is
      set.

    + main.c (main): Prevent curbp from pointing to an already
      freed memory area.

    + x11.c (sel_prop, selection_data, selection_len): Removed these
      fields from struct _text_win.

      (atom_TARGETS, atom_MULTIPLE, atom_TIMESTAMP, atom_TEXT): Added
      variable declarations and initialization statements for these
      atoms.  Initialization is performed in x_preparse_args().

      (free_selection, x_stash_selection, strndup): Deleted  these
      functions.

      (x_get_selection, x_paste_selection, x_get_selected_text,
      X_convert_selection, x_lose_selection, own_selection): New or
      rewritten functions to use the Xt Intrinsics instead of Xlib for
      handling selections.  In particular, xvile now handles the
      following targets: TARGETS, MULTIPLE, TIMESTAMP, STRING, and
      TEXT.  xvile should now be ICCCM compliant with respect to
      selection handling.

      (x_process_event): Removed all selection handling code.

      [ Thanks to Brian Schellenberger ([e-mail]) for
        contributing code which made xvile more ICCCM compliant.  I
        used his contribution as a framework for x_convert_selection().

        Chan Benson's "Implementing Cut and Paste in the X Environment"
        (The X Resource, Issue 10) was also instrumental in making the
        above changes. ]

    + buffer.c (make_current): Prevent the buffer hook from being run
      if we're presently reading from the message line.  In particular,
      this will prevent the buffer hook from running when the
      Completions buffer is popped up.  (:set and :setv were adversely
      affected since these operations are often performed from one of
      the buffer hooks and they are not reentrant.)

    + filec.c (fillMyBuff): Changed the algorithm for non-VMS machines
      to use qsort() (via sortMyBuff) instead of an insertion sort.  On
      a 100 MHz pentium, this caused the cpu time needed to build a
      completion list for a directory of roughly ten thousand files to
      go from approximately 3 minutes to a mere 2 seconds.  (I know
      that 10,000 files seems like a lot.  But one of my coworkers
      discovered this performance deficiency in a directory with over
      32,000 files.  xvile needed in excess of 14 minutes of cpu time
      to build the completion list on a SPARC-20.)

    + filec.c (qs_pathcmp, sortMyBuff): New functions.

    + vile.hlp: Minor corrections.

    + select.c (attributeregion): Only allocate memory for new attribute
      when actually adding new attribute.  attributeregion() is also
      responsible for deleting attributes.

    + bind.c (engl2fnc): Make sure the binary search terminates.  Setting
      shell variable VILEINIT to ./vileinit would cause engl2fnc() to
      loop endlessly.  I now know that this was not the proper usage
      of this environment variable.  But engl2fnc() still shouldn't
      get stuck in an infinite loop.

    + eval.c (gtenv, SetVarValue): Make sure that curbp is not NULL
      prior to using it.  This can happen during the execution of
      .vilerc.  The resultant behavior is not necessarily what the user
      expects, but at least it doesn't cause a core dump.  For example,
      put the following into your .vilerc:

          ~if &seq $progname "xvile"
            set title $cfilname
            set iconname $cbufname
          ~endif

      I think the expected behavior would be to have $title and
      $iconname in xvile take on the values of $cfilname and $cbufname
      respectively.  But curbp is NULL when these actions are
      performed.  I don't dare move any of the initialization code in
      main() around or something else'll break.  [I'm not really all
      that bothered by this behavior.  The "buffer-hook" variable works
      well for this type of stuff.]

    + fences.c (InDirection, simple_fence, fmatchindent): Fixed problem
      in which closing right curly bracket was not getting indented
      properly in cmode.

    + input.c (kbd_reply): Don't erase default message if a completion
      character is entered.  This takes Tom's fix to this code somewhat
      further.  Scenerio: I enter ":e ../vile-5.3/fil<TAB>".  It only
      completes to ../vile-5.3/file.  At this point I too hastily hit
      return (having mistakenly expected the completion to be unique).
      I realize my error and hit ":e " I see ../vile-5.3/file.  I press
      <TAB> and see the other completions (I have popup-choices set to
      immediate).  I see the other completions and expect to be able to
      modify the default response since I _have_ pressed a key _and_
      the default response has not been erased.

    + main.c (main): Fixed a small bug introduced in 5.3g which caused
      xvile to core dump when given no arguments.

    + main.c (cmd_mouse_motion,loop): Permit cursor to rest on the
      newline if it was placed there via the mouse.  This permits
      the pasting of text at the end of the line.

(pgf)
    + get rid of #elif in display.c, for K&R compiler on HP/UX.

    + set "scanbound_is_header" flag in oneliner.c when doing
      line substitutions.  fixes broken :s/foo/bar/ commands.
      (search.c, oneliner.c, edef.h)

    + applied lee johnson's fixups to my changes for OS/2. (estruct.h,
      os2vio.c)

    + change name of variable used to cache interruptible pipe-read
      results.  variables must contain '_cv_' to work correctly.  this
      speeds up subsequent configure runs quite a lot, since the
      pipe-read test is a looong one.  (aclocal.m4)

    + applied fixes from purify'ing on HP from Warren Vik (path.c,
      map.c)

    + protect against null filenames (with BUG: report) in readin().
      (file.c)

    + add another OS/2 specific errno check to ffropen() (fileio.c)

    + turn on prototypes for OS/2 and IBM compiler in mktbls.c

    + set [Messages] buffer invisible and active to a) keep it from
      being found by ":n" and b) keep readin() from being called on it.
      (msgs.c)

    + eliminated references to vmalloc code.  i haven't used it in
      years, and there are better debugging libs available.
      (estruct.h, exec.c, file.c, makefile.in, undo.c)

    + added ".cc" to the default cmode suffixes. (main.c)

    + changed the deblank() routine to a forceblank() routine -- with
      no arg still removes blank lines, but with an arg will force
      that many blank lines at current point.  can be used to quickly
      double-space some text, for example.  (random.c, cmdtbl, vile.hlp)

    + minor change to help re-display code to better preserve DOT across
      help invocations, and to prevent spurious moves if help is reinvoked
      while still on-screen.  (bind.c, buffer.c, edef.h)

    + remove usage of gets() from c-filt.c  (on recommendation of
      runtime warning from gcc on freebsd...  imagine my surprise :-)

    + fix c-filt.c to correctly recognize keywords which contain
      spaces after the '#', as in:
          #if foo
        #  define bar
        #endif

    + clean up bufhook so that the hook won't be called too early
      in the case of being invoked from swbuffer.  that is, we
      keep make_current from invoking the hook, since swbuffer
      isn't ready (curwp may not be set up yet).  this let's
      me run the C-filter macro as a buffer-hook.  (buffer.c)

    + added the "< register, which contains the last few hundred
      keystrokes typed.  actually, it will contain somewhere between
      128 and 256 characters, since its limited to a single dchunk.
      (estruct.h, map.c, line.c, vile.hlp)

    + added "dotags" and "devonlylist" targets to makefile.

    + applied patches to make ^T do a proper shiftwidth in insert
      mode.  also be sure insertmode doesn't get reset by functions
      called from insertmode.  (from grant mcdorman)  (insert.c)

    + modify xterm-mouse code to allow its use with TERMs other
      than xterm.  currently, if it's not really an xterm, then
      the mouse reports are assumed to be zero-based rather than
      one-based.  apparently some Amiga terminal emulator does
      this.  this can be generalized if needed.  (from grant mcdorman)
      (tcap.c)

    + c-filt.c now supports "Literal" attribute, for highlighting
      strings.  (c-filt.c, vile.hlp) (from ben stoltz)

    + applied patch to support '?' searches in tags files.  (tags.c, from
      eric krohn)

    + implemented nvi-style infinite undo, which overloads '.' command
      to continue undoing changes, if it immediately follows an undo.
      added status message to help figure out which way (forward or
      backward) you're going.  (cmdtbl, undo.c, main.c, vile.hlp)

    + gave line_report() return value indicating whether it printed
      message or not.  (random.c, line.c, globals.c, proto.h)

    + suppress compiler warning in glob.c

    + changed "Only one occurrence.." message to not beep, and not cause
      popup messages if you hit it during startup.  this also means "terse"
      mode will suppress it. (search.c)

    + removed some dead "ifdef BEFORE" code and commented lines.  (undo.c
      basic.c bind.c insert.c line.c)

    + added gppconio.c to the distribution.  one of these days maybe
      this can go away, when the fixes are incorporated in the djgpp
      release.

    + changed the test code in aclocal.m4 to always try and include
      ioctl.h and sys/ioctl.h.  this makes it match the usage in
      fileio.c.  the test code didn't have ioctl.h, therefore thought
      we needed our own extern for ioctl(), and ours doesn't match
      the freebsd prototype (theirs is variadic).  i seem to only
      have autoconf 2.2, so if someone wants to rebuild configure
      with 2.3, that's fine with me.  (aclocal.m4, configure)

(tom)
    + corrected ifdef in path.c that broke vms compile.

    + added configuration tests for prototypes, varargs.

    + corrected missing flag in 'gotoline()' that caused reframing error
      (basic.c).

    + corrected off-by-one that made 'N' fail for pattern "." (search.c).

    + added '\' and ':' to pathname-characters for MSDOS (main.c).

    + corrected handling of "--with-CFLAGS" (configure.in)

    + corrected allocation-size in resolve_dir (path.c)

    + corrected logic of binary-search version of engl2fnc (bind.c)

    + corrected off-by-one errors in text yanked by goto-matching-fence
      command (fences.c, select.c).

    + corrected translation of SEL_KREG in 'index2reg()' from '{' to '.'
      (line.c).

    + modified button1-release in xvile to yank the selection (x11.c).

    + corrected 'updattrs()' to not highlight text that cannot be selected
      e.g., line numbers (display.c)

    + compiler warnings for DEC-C and Watcom 10.0a (estruct.h, fences.c,
      filec.c, mktbls.c, npopen.c, os2pipe.c, os2vio.c, path.c, proto.h,
      random.c, spawn.c, termio.c, vmspipe.c, vmsvt.c) on OpenVMS and OS/2.

    + modified quoted-motion to interpret repeat-count as code for type of
      selection: 1=exact, fullline=2, rectangle=3 (select.c).

    + modified xvile to _not_ start display if only a "-V" option is given
      (main.c).

    + removed 'slash-char' mode, modifying code to use '/' for internal use
      of MSDOS pathnames (filec.c, glob.c, modetbl, main.c, modes.c,
      path.c, random.c).

    + modified name-completion so that if we match _something_, typing a
      character won't erase the buffer (input.c).

    + revised manpage filter to allow for escape sequences that set
      boldface/underlining -- this happens on OSF1 (manfilt.c).

    + corrected code that supports OPT_XTERM >= 3 -- this is mostly for use
      in demos since we don't handle text-position reports in :-commands,
      for example (tcap.c).

    + modified VALNAMES structure to have a side-effects function pointer,
      replaced the inline logic in mode-setting with a table (modes.c,
      modetbl, mktbls.c).

    + modified logic that set up name-completion table for the combined
      modes + variables to suppress "no"-prefix, etc.  Made related
      changes to ensure that vile prompts for boolean modes set via ":setv"
      (eval.c, input.c, modes.c).

    + corrected logic that updates command-line display during name
      completion (bind.c).

    + modified mode-value completion to include booleans and colors, if the
      enumerated value code is configured (modes.c).

    + modified so that vile will prompt for reloading tags buffers when
      user uses ":e" to view the buffer (file.c).

    + modified to show the actual filename for the help-file (bind.c).

    + modified to remember position in help-file when re-reading it (bind.c,
      buffer.c).

    + corrected adjust_forw, adjust_back functions to avoid returning
      non-line location which broke reframing (window.c)

    + corrected test in 'reframe()' for case where wrapped line was larger
      than the window (display.c).

    + modified to use w_line.o to store offset so that current position in
      wrapped lines that are larger than the window still displays
      (display.c).

    + added configure test for ANSI_QSORT (aclocal.m4).

    + modified test for nsl library to see if it's needed; otherwise this
      breaks xvile on IRIX 5.3; the standard X library configure test may
      also add this library (configure.in).

    + linted on solaris and irix -- conversion and constant-conditional
      (lots of places).

    + make the case-insensitive code for WINNT a configuration option

    + modified logic to make fake window & buffer to satisfy references
      before vile starts screen mode (main.c, window.c).

    + added "dumb" terminal driver to allow for prompting before vile
      starts into screen mode (main.c, termio.c, dumbterm.c).

    + modified file-completion on VMS to use kev's qsort improvement
      (filec.c)

    + corrected version-parsing for VMS filenames (vms2unix.c)

    + corrected VMS filename-completion when user supplies "/" (filec.c).

    + modified most exit-calls to do 'vttidy()' first (file.c, ibmpc.c,
      main.c, vmsvt.c, version.c, termio.c)

    + modified test-scripts for VMS to work across devices (descrip.mms,
      vmsbuild.com).

    + moved terminal/keypad-initialization into TTkopen(), and the matching
      resets into TTkclose() so that "vile -V" works properly with the
      dumb-terminal driver (tcap.c, termio.c).

    + corrected off-by-one error in VMS shorten_path that caused ../SIO to
      be shown as [-.IO] when cwd was ../SRC (path.c)

    + enabled directory-completion for VMS (estruct.h).

    + removed some ifdefs for apollo and CenterLine C that should be
      obsoleted by the 'configure' script (estruct.h).

    + moved TTkclose/TTkopen calls in fileio.c down to where they're
      actually used -- spawning subprocesses -- to avoid spurious
      reinitialization of the terminal in termcap mode (fileio.c,
      npopen.c).

    + corrected motions '(' and ')', which did not handle empty lines
      like vi (basic.c).

    + corrected handling of command-line '+' when argument is greater
      than buffer length, and also ensured that initial-search string
      doesn't conflict with contents of .vilerc (main.c).

    + corrected logic of regstrchr, which did not skip '\' characters for
      range-expressions.  This caused pattern "[<>]" to match '\' also
      (regexp.c).

    + modified ibmpc drivers to update current_res_name, so that vile will
      restore the screen resolution after spawning a command (borland.c,
      ibmpc.c).

    + corrected logic for $buffer-hook so that it's not invoked unless the
      buffer is the current window, so that editing commands work
      (buffer.c).

    + modified logic to enable 'readin()' to run $read-hook when reading
      from a pipe -- which concludes with an FIOEOF code (estruct.h, file.c)

    + corrected logic that sets the first buffer-pointer so that startup
      scripts can manipulate it.  This implies that we'll always create the
      unnamed buffer, just in case it's needed, and remove it after reading
      .vilerc if it's unmodified.  Also remove, if possible, any stray
      windows belonging to the unnamed buffer if a named buffer is
      available, just in case .vilerc created windows (main.c).

    + modified ffexists/ffaccess to check that their argument is really
      a valid pathname (fileio.c).

    + corrected logic that closed [History] buffer, which was resetting
      'autobuff' mode, and warning message if :show-history was given when
      history mode was off (history.c).

    + corrected the check I'd added to ffexists/ffaccess (I'd used
      maybe_pathname, which was requiring pathname-delimiters) to use
      isInternalName instead (fileio.c).

    + modified logic in execute-named-command to prevent accidental
      invocation of commands (such as ":q!") when the command is terminated
      by unexpected character (such as <esc>) (exec.c).

    + corrected logic that sets last_eolchar when interpreting macros,
      so that commands such as "set nu lw" will work (input.c).

    + modified logic so that saving the unnamed buffer to a file renames
      the buffer (file.c).

    + made mouse work for msdos+watcom configuration using polling (estruct.h,
      ibmpc.c)

    + updated makefile for watcom 10.0a (makefile.wat)

    + corrected logic in wrap_at_col(), which sets the column at which the
      wrapmargin mode activates; I'd used 'col_limit()' in an expression,
      which broke when linewrap was set.  Also checked for end-of-line
      before wrapping; this was an error in 'o' (insert.c).

    + modified interface of 'getccol()' and 'getcol()' to pass 'list' mode
      for the special case of testing wrapmargin (insert.c, random.c, etc).

    + rewrote manfilt.c to handle more general escape and underline sequences
      (manfilt.c).

    + refined treatment of wrapmargin to trim trailing whitespace when a
      tab/space is inserted past the wrap-margin.  This still isn't
      _exactly_ what vi does (insert.c, word.c).

    + corrected handling of ^D/^U/^F/^B scrolling commands for long wrapped
      lines which weren't doing anything if the screen didn't display at
      least two lines, and final position of ^B, which wasn't going to the
      top of screen (basic.c)

Changes for vile 5.3 (released Tue May 09, 1995)
(pgf)
    + implemented "watchinput" arg for the poll code in catnap().
      (random.c)

    + fixed the definition of VDISABLE to attempt to use _POSIX_VDISABLE
      before using our own value. (termio.c)

    + cleaned up path lookup (flook()) code, and the code that tries
      to find our executable.  previously, we didn't know where the
      executable was until someone used the ":version" command.  and,
      we assumed that argv[0] could always be used to find us.  but
      if argv[0] contains no slash chars, we can make no assumption
      about where we came from.  there are still some problems in here,
      because i think we sometimes try to run access() on things that
      aren't quite pathnames yet.  (bind.c epath.h estruct.h main.c
      path.c proto.h version.c)

    + correct behavior of forwline()/gotoline() so that we get an error
      if we try to go to a line beyond the end of the buffer.  (basic.c)

    + don't check for '\r' on empty lines when counting doslines. (file.c)

    + fix ".bak" style backups when the filename is of form ".foo".  now
      change this to ".foo.bak" rather than just ".bak".  (UNIX only)
      (fileio.c)

    + added TI/TE and KS/KE processing to tcapk{open,close}.  i don't
      know that this is always right, but it fixes an xterm arrow key
      bug in some cases.

    + removed TI/TE part of above change.  it's not always right.  the
      terminal open/close code needs serious examination.  sigh.

    + removed broken ULTRIX ifdef in x11.c, which tried to support
      KEY_Remove.  it was broken.  i _could_ make it work, but i
      don't know what i'd bind it to.  (x11.c)

    + fixed "arrow key during insert" bug introduced in 5.2, which
      prevented arrow from moving beyond EOL when inserting.  (basic.c)

    + vile will now warn and insist on ":q!" if not all edited buffers
      are visited during the edit session (i.e. some are still
      "unread").  this is for vi compatibility, since some people use
      "ZZ:n" when moving through their files, and vile was quitting
      after the ZZ.  (the routine anycb() has been renamed
      any_changed_buf() as well.)  (main.c, buffer.c)

    + a new mode, "warn-unread", which will suppress the above behavior
      if it is turned off.  (modetbl, main.c)

    + implemented "visual-matches" mode, which allows one to highlight
      all matching occurrences of a search string when doing a search.
      that is, if i search for "foo", then all occurrences of "foo" in
      the buffer will be highlighted (as specified by the value of
      "visual-matches").  i did not allow for color -- only bold,
      italics, underline, and reverse are supported.  this can be
      added in the future, i suppose.  (modetbl, modes.c, main.c,
      search.c, undo.c, estruct.h, vile.hlp)

    + added command to clear visual-matches:  "clear-visual-matches",
      bound to '=' by default. (cmdtbl, search.c)

    + added concept of "ownership" to attributes, so that, for example,
      search-string attributes can be cleared independently of selection
      attributes or ctl-A sequence attributes.  (select.c, search.c,
      estruct.h, display.c)

    + added/changed text in README.CFG which describes what to do
      when configure or the make doesn't work.  (README.CFG)

    + reset the action of VDSUSP char under POSIX.  (termio.c)

    + applied patch from rick sladkey, for borland.c fixups and djgpp
      compilation:

        Part 1: borand.c enhancement and bug fixes
        + enhance borland.c so that scrolling regions are used
          efficiently

        + enhance borland.c so that individual characters are buffered
          which makes certain conio packages much faster (e.g the DJGPP
          one)

        + enhance borland.c to handle PC-style function keys (e.g.  F1,
          F2, PageUp)

        + make the cursor-toggling code in borland.c, generic, optional
          and turned off by default since a big blinking block is
          horribly ugly

        + fix the color handling in display.c so that the broken and
          unusable garbf kludge in bor?color in borland.c is no longer
          needed

        + fix erase to end of page in borland.c so it actually works

        + enhance the mode detection in borland.c so that the screen
          mode does not need to be changed in the default case (i.e.
          when using the current mode)

        + prevent borland.c from clearing the screen on exit so it is
          like vile on every other display device (i.e it goes to the
          lower left instead)

        Part 2: misc bug fixes affecting the MS-DOS versions

        + change the default msdos slash character to '/' instead of
          '\\' because typing tab (for completion) after backslash
          inserts a ^I instead which makes completion under MS-DOS much
          less useful and fairly annoying

        + fixed a null pointer dererencing bug in main.c which occurs
          when the vile.rc file is being edited but it does not exist
          yet

        + enhanced makefile.djg so that either ibmpc.c or borland.c can
          be used and so that borland.c is used by default

        + fixed a bug in path.c that caused the first slash after a
          drive letter not to be canonicalized properly (e.g.
          C:\FOO\BAR => c:\foo/bar)

        + fixed a bug in path.c affecting DJGPP that caused relative
          pathnames containing an explicit pathname to be corrupted
          (e.g.  C:FOO => ../:/foo) by deleting incorrect code whose
          intention is solved by the previous fix

        + omit a conflicting prototype for delay which I don't know who
          needs but it can't be used as is on all platforms

        + fixed a fairly serious bug in file.c that causes the file
          size to be computed incorrectly at startup on dos-mode files
          which caused an explicit write of an unmodified buffer to
          append garbage to the file because the size was overstated by
          the number of returns in the file which have already been
          deleted but not yet subtracted from the count

    + further changes to make rick's changes work okay under watcom.
      the DOS path-deliter is now selectable, with "set slash-char".
      (edef.h, estruct.h, file.c, filec.c, fileio.c, glob.c, input.c,
      modes.c, modetbl, path.c, proto.h, random.c, vile.hlp)

    + added in patch from Russ Herman which fixes kbhit() problem with
      function keys in OS/2.  (borland.c)

    + eliminate FAIL macro in regexp.c, since it saves very little,
      and is hard to write correctly without _someone's_ compiler or
      lint complaining about it.  (regexp.c)

    + fix infinite loop caused by null search patterns (e.g. ".*" or
      "^".  (estruct.h, search.c)

    + got rid of vestigial "tungetc()" code.  (input.c, proto.h, edef.h)

    + fix (quickly) the broken @a-in-a-macro problem. (map.c)

    + added ifdef'ed code which allows logging all keystrokes to
      a tempfile, which can help when trying to recreate rare bugs.
      (map.c)

    + modify regstrncmp to take use system strncmp when possible.
      (regexp.c)

    + made "fence" characters (i.e {,}.(,),[,]) configurable by
      user (new mode, "fence-pairs"), so that < and > can be added
      easily (i hear this is useful for html editing).  (fences.c,
      insert.c, main.c, modes.c, modetbl, proto.h, vile.hlp)

    + added patch from anthony shipman, to keep X11 selections from
      starting unless at more than one char is swept.  (x11.c)

    + added a binary search to engl2fnc, but it's not quite right.  i
      was in a hurry.  it's ifdefed.  (bind.c, externs.c)

    + minor efficiencies in regstrncmp and regstrchr.  (regexp.c)

    + interrupted() is now a macro again, when appropriate.  this
      speeds up simple searches to run something like 10% faster.
      (main.c, edef.h, estruct.h, proto.h)

    + fix cosmetic message bug when 'q' command is ended immediately
      with another 'q'.  (select.c)

    + fix forwchar() to work as advertised.  from a user's point
      of view, it now skips the newline if no arg is given, so it
      can move across lines.  this meant some places where it was
      called with default args internally had to be changed.
      (basic.c, word.c)

    + force an update() in reposition(), so that "redraw-display"
      can be used in a macro to force an incremental screen update.

    + fix typo in cmdtbl.

    + created pictmode.rc, a primitive "mode" which assists in
      drawing ascii "art".  not that i've used it much yet...

    + changed cbuf[2] in replacechar() to cbuf[NLINE].  apparently
      the length arg that is supposed to prevent overruns doesn't
      work, if you do a command like "replace-char %keywas", i.e.
      use a variable to provide the response. (insert.c)

    + added ISO-8859 characters and punctuation to ispunct() etc.
      classes in charinit().  i assume this is "right".  (main.c)

    + applied patches from Lee Johnson ([e-mail]) for
      support of OS/2 from the IBM C Set ++ Compiler (2.x).  changes
      mostly to pipe support, directory access, and file completion.
      new makefile (makefile.icc), new screen (os2vio.c), and new pipe
      routines (os2pipe.c).  (borland.c, buffer.c, dirstuff.h,
      display.c, edef.h, estruct.h, file.c, filec.c, fileio.c, glob.c,
      makefile.in, mktbls.c, modes.c, npopen.c, path.c, proto.h,
      random.c, spawn.c, termio.c, version.c)

    + fixed --with-cflags option to configure script (configure.in,
      configure)

    + add another mention of ctrl-button functions, in the button
      section of help file.

(tom)
    + modified configuration scripts to conform to autoconf 2.2
      (aclocal.m4, configure, configure.in, dirstuff.h).

    + modified select.c to recover from manfile error that produces
      empty attribute-region (select.c).

    + removed "#error" for SunOS's K+R compiler (line.c).

    + modified to make OPT_MAP_MEMORY and SMALLER configurations compile
      (cmdtbl, display.c, search.c

    + modified tmp.c to use calloc on page/chunks to appease Purify.

    + added auxiliary programs to lint-rules (makefile.in).

    + use void-casts for strcmp, lsprintf, etc., (lots of places), and
      FALLTHROUGH comments for SunOS and IRIX lint (display.c, main.c,
      oneliner.c, wordmov.c)

    + removed redundant ';' after FAIL() macros that causes IRIX lint
      warnings in (regexp.c).

    + mods for miscellaneous lint (csrch.c, exec.c, filec.c, insert.c,
      main.c, modes.c, proto.h, region.c, tcap.c).

    + added stdarg.h to configure.in test so ANSI_VARARGS will work.

    + modified lint ifdef's for ANSI_VARARGS <stdarg.h> case, tested
      with IRIX lint (estruct.h).

    + added configuration tests for 'errno', 'time_t', 'off_t'
      (configure.in, aclocal.m4).

    + split-out neproto.h (from nefunc.h); cleanup gcc's -Wnested-externs
      and -Wredundant-decls warnings (mktbls.c, estruct.h, proto.h, etc.)

    + use IRIX lint to find/modify functions that can be made static
      (proto.h and several modules...)

    + corrected logic in makefuncdesc() and fnc2kcod() that caused vile to
      ignore the user-defined key bindings (bind.c).

    + modified mlreply_file() to handle the ^R!shell-command case (filec.c)

    + corrected ifdef that broke 'slash-char' mode when compiling
      SMALLER (main.c, modes.c).

    + modified wildcard-expansion for VMS to handle comma-separated lists,
      and /readonly option.

    + corrected tab offset in 'vtputc()' so that linewrap displays properly
      with various tab sizes (display.c).

    + added ifdef to use MAXPATHLEN if it is defined in <sys/param.h>
      (estruct.h).

    + adapted code by kev to resolve directory names which may contain
      embedded symbolic links (path.c, configure.in).

(kev)
    + display.c (l_to_vcol): Make sure that we don't try to examine
      characters which are past the end of the line.  Also compute
      non-varying parts of the loop condition in advance for efficiency.

    + configure.in: Don't use grep to pick out -D lines since some
      versions of grep limit the number of characters which are output.

    + search.c (attrib_matches): Start DOT out at the head of the buffer
      to attribute matches for instead of at the first line.  This will
      cause the first character in the buffer to be highlighted if
      deserving.

    + search.c (attrib_matches): Added new code for attributing with
      color.

    + modes.c (fsm_mono_attributes): Added color to this list.  Hmm...
      "color" doesn't seem to be a "mono" attribute, does it?


Changes for vile 5.2 (released Thu Feb 23, 1995)
(pgf)
    + added vile-c-filt to the man page.  (vile.1)

    + remove root cause of"C<right-arrow>c" core dump -- no longer
      allow an extra amount of right-motion just 'cuz we're in insert
      mode.  whatever the reason for this extra was, it doesn't seem
      to be necessary anymore.  recoded remaining conditions for
      clarity.  (basic.c)

(kev)
    + estruct.h (OPT_COLOR): Don't define in terms of DISP_X11.  This
      fixes the ":set all" core dump.  OPT_COLOR indicates that the
      older (line-by-line) color mechanisms should be used.  These
      mechanisms are stubbed in x11.c, but are not implemented (and
      probably won't be).  My recent change to NCOLORS (for DISP_X11)
      made some OPT_COLOR ifdef'd code in modes.c break (there are only
      eight entries in the cname array but there are now sixteen
      colors.) So rather than put NCOLORS back to 8, it seemed more
      expedient to simply disable all of the OPT_COLOR code which xvile
      was never able to make use of anyway.  We should also probably
      take the OPT_COLOR related ifdefs and stubs out of x11.c.

      (VIDEO_ATTR): Make sure that this is typedef'd to be a short
      when DISP_X11 is defined.

(tom)
    + corrected core dump when user types "C<right-arrow>c" (line.c).

    + change "defined(sun)" to "SYS_SUNOS".  (finderr.c)

Changes for vile 5.1 (released Tue Feb 21, 1995)
(pgf)
    + fix longstanding bug when keyboard macro is executed while
      it is being recorded.  (input.c)

    + fixed broken beginDisplay/endofDisplay nesting in xterm-mouse
      code, which caused lockups after a resize operation. (tcap.c)

    + fixed misspelled ifdef which caused filename truncation when using
      "tilde style" backups.  (fileio.c)

    + changed "X11" to "DISP_X11" in vmsbuild.com and descrip.mms.

    + fixed OPT_REVSTA ifdefs so modeline reverse-video can be turned
      off.  (display.c)

    + trimline() can be called with DOT.o == llength(lp), for instance
      if a macro calls "end-of-line" followed by "append-string" where
      the string starts with a CR.  trimline() was trimming (or not,
      didn't matter), and then backing DOT.o up to the last char on the
      line.  the CR would then break the line, instead of appending to
      it.  this is probably a problem in other functions as well, if
      called from a macro, since we don't do the "DOT.o can't sit on
      the newline" hack while executing macros.  (region.c)

    + replaced contents of c-filt.c with x-filt.c.  it seems to be a
      full superset of its functionality.  it is now installed along
      with manfilt, as vile-c-filt.  the help file now talks more about
      it.  (c-filt.c, makefile.in)

    + documented the color.[fb]color[1-16] subresources. (vile.hlp)

    + included the c-filt.flx code contributed by alistair crooks in
      the distribution.  (c-filt.flx, makefile.in)

    + changed the "built" names of manfilt and c-filt to vile-manfilt
      and vile-c-filt, to match their installed names, and to match
      the documentation. (makefile.in)

    + changed the new color resources to be {f,b}color[1-9,10-15],
      rather than A-F as before. (x11.c)

    + turned off IBM_VIDEO for linux.  it's not necessarily true.
      turned on OPT_COLOR for linux and DISP_TERMCAP, which is what we
      were trying to imply with the above anyway.  (estruct.h)
(kev)
    + patchlev.h (PATCHLEVEL): Updated to "c".

    + x11.c (update_scrollbar_sizes -- NO_WIDGETS version):
      Restructured loop which allocates new scrollbars and grips
      somewhat.  In addition to no longer creating one more grip than
      necessary, we also explicitly check to see which grips need to be
      created.

    + x11.c (check_scrollbar_allocs): Allocate the same number of grips as
      scrollbars.  We don't actually need this many, but allocation in this
      manner caused some subtle allocation problems with GROW().  GROW() was
      being called as follows:
          GROW(cur_win->grips, Widget, oldmax-1, newmax-1);
      When cur_win->grips is initially allocated, cur_win->grips is
      NULL, oldmax is 0, and newmax is cur_win->rows/2.  Note then that
      -1 is being passed as the third parameter to GROW().  This causes
      newmax elements (rather than newmax-1 elements -- the number of
      elements allocated) to be zero'd near the end of the grow macro.

      The other piece of code affected (adversely) by this allocation is
      in update_scrollbar_sizes() where new scrollbars and grips are
      created.  It turns out that one more grip than necessary is created.
      Under certain conditions, the GROW macro would zero out this extra
      grip.  When reinvoked, update_scrollbar_sizes() would assume that
      this extra grip had been created and not bother to recreate it.

      + patchlev.h (PATCHLEVEL): Updated to "a".

    [ Note: The following changes constitute the merge of Jukka Keto's
      changes for color support to xvile.  Thanks Jukka! ]

    + estruct.h (OPT_COLOR): Define in terms of DISP_X11, not X11.

      (NCOLORS): Conditionally define this to be 16 instead of 8.

      (VAFGCOL, VABGCOL): Removed.

      (VACOLOR, VCOLORNUM, VCOLORATTR): New defines.

    + select.c (attribute_cntl_a_sequences): Color support.

    + x-filt.c: New file.  This is Jukka's syntax coloring filter for C
      programs.  I modified it slightly to compile clean under gcc with
      Tom's favorite warning flags: -Wall -Wshadow -Wconversion
      -Wstrict-prototypes -Wmissing-prototypes.  Also fixed a problem
      with "'".  It also no longer requires an ansi compiler.  Note: It
      should probably be merged with c-filt.  A command line switch to
      [xc]-filt could be used to indicate whether monochrome or color
      should be used.

    + x11.c (struct _text_win): New fields colors_fgc, colors_bgc,
      colors_fg, and colors_bg.

    + (Xt{N,C}{f,F,b,B}color{0-9,A-F} i.e, XtNfcolor0,...): New
      resource defines.  Kind of ugly to have to declare all of
      these like this, but that seems to be the way its done.

      (color_resources): Structure which defines the color subresources.

      (x_preparse_args): Get the color subresources and initialize
      the color GCs.

      (x_setfont): Set new font for all of the color GCs.

      (flush_line): Handle color attributes.  Also check for the
      most common (default) attribute first for efficiency.

(tom)
    + corrected end-of-line problem with autoindent that broke 'append-string'
      (insert.c).

    + turn off 'access()' function for DEC C on a VAX as per bug report
      by [e-mail] (estruct.h).

    + added arrow-key definitions for VAX (vmsvt.c).

    + corrected treatment of underlining in termcap driver (tcap.c).

    + implemented termcap-based colors (tcap.c).

Changes for vile 5.0 (released Fri Feb 10, 1995)
(pgf)
    + rearranged ifdefs leading to OPT_WORKING def'n for clarity.
      (estruct.h)

    + a couple of the new scratch buffer names were too long.  (edef.h)

    + added commands for undoing system maps ("unmap-system-chars")
      and abbreviations ("unabbreviate").  (map.c, cmdtbl,
      vile.hlp, proto.h)

    + NetBSD, FreeBSD, etc. all seem to define the termcap "kD" attribute
      as DEL.  i consider this questionable, since they also produce
      DEL from the Backspace key, but in any case, it means we shouldn't
      define a system map for the DEL key.  we should really have separate
      system maps for insert and command modes, but i think that might be
      overly complicated.  so instead, i suppress the mapping of an ASCII
      DEL to anything else (at the system level -- the user can still do
      whatever they want.)  (tcap.c)

    + renamed our signal() wrapper to setup_handler(), and always use it.
      on systems with sigaction(), use it in place of calling signal() to
      ensure system calls are restartable.  setup_handler() is now in
      main.c, moved from termio.c (buglist, display.c, file.c, main.c,
      proto.h, spawn.c, termio.c, x11.c, x11simp.c)

    + use test for restartable reads on pipes rather than stock
      restartable system call test, when trying to configure OPT_WORKING.
      OSF/1 3.0 has restartable system calls, but reads (and writes) on
      pipes will return EINTR regardless of SA_RESTART state.  they
      call this a feature, based on the POSIX spec.  i haven't been
      able to check.  (if you link against -lsys5 on OSF/1, you _can_
      turn on OPT_WORKING.  but they claim that may be a bug, and
      a "libsys5.a" may exist on other system, so i'm not going to
      trust or use it.) (aclocal.m4, configure, configure.in, estruct.h)

    + pasted characters now have the NOREMAP bit set, to prevent map
      expansion of pasted text. (x11.c, estruct.h)

    + changed token parsing to no longer treat ^L and ^M (i.e. formfeed
      and carriage return) as whitespace.  this fix is mostly for :map,
      so that carriage returns can appear in the lhs and at the start
      of the rhs, but it should also allow those characters in other
      response contexts as well.  (exec.c)

    + implemented "flow-control-enable" command, which re-enables
      software flow control for those users who still need it.  not all
      implementations (posix/sgtty/termio) were disabling it in the
      first place -- i'm surprised selections worked there (they may
      not have.) (termio.c, cmdtbl, proto.h, vile.hlp)

    + protect against infinite recursion when attempting to print
      0x80000000 as a signed integer.  (display.c)

    + changed file completion buffer to show the full prefix of the
      thing that's being completed (patch from jukka keto). (bind.c)

    + added jukka keto's c-filt.c program to the distribution. (c-filt.c,
      makefile.in)

    + changed HAS_ALARM define to HAVE_ALARM, and let it be autoconf'ed.
      (estruct.h, configure.in, configure)

    + added code in ffgetline(), which is where pipes are read, to
      check for EINTR from a SIGALRM and redo the read() if we're
      on a system where the read() isn't restartable. this lets
      us turn on working on all system that have alarm(). THEN, i
      backed this change out with ifdefs, since i think some old
      kernels can lose data if they get a signal during a
      read().  (fileio.c, display,c, estruct.h, edef.h)

    + put start of child process status reporting in system_SHELL().
      ifdef'ed it out, since the WIFSIGNALED etc. macros probably
      aren't on all systems, and i don't want to break this release.
      (npopen.c)

    + introduce checks for SCO systems, which are probably not so odd
      when compared with their peers, it's just that their peers have
      all gone away.  (configure.in, configure, termio.c, estruct.h)

    + fix globbing in root directory (i.e. ":e /j*k" now gets "/junk"),
      and move DOS check for this same thing ("c:auto*.bat") slightly.
      ensure what we don't end up with doubled or trailing slashes
      ("//foo", "/foo/") anywhere, since DOS won't open those or stat
      them properly.  (glob.c)

    + fixed benign wp/curwp mixup in l_to_vcol().  (display.c)

    + change expression for lint. (map.c)

    + move ifdef for ANSI_QSORT into estruct.h, so it can be used in
      proto.h as well as glob.c (proto.h, glob.c, estruct.h)

    + added a couple of SIZE_T casts to keep "new ansi semantics" warnings
      at bay.  (file.c, history.c)

    + fixed some typos in the vile.hlp, added a version number, to
      correspond to the version it's distributed with.

    + change name of __MAXINT to not have __ on front, add cast to (int).
      (display.c)

    + changed the FL_PATH search order to look in the table first.  this
      a) seems more correct, and b) will help ensure that the new helpfile
      location (/usr/local/lib) will be checked before the old (which was
      /usr/local/bin).  took /usr/local/bin out of the internal table.
      i have more changes pending for this area, having to do with bugs
      in how we determine where the executable came from.  but i'll hold
      them until next release.  (bind.c, epath.h)

    + added note about old helpfiles to README and README.CFG.

    + added some more reminders for myself to the release_warnings
      target. (makefile.in)

    + created patchlev.h file.  include and use it it in version.c.

    + added missing range checks to EXACTLY case of regrepeat() to
      prevent going off end of line when matching 'cc*' on a line
      that ends in 'c'. (regexp.c)

    + fixed ifdefs for signal_pg(), to negate pid when killing a pgrp
      with kill().  (estruct.h)

    + moved setting of new process group out of x_open(), and into a
      command, which can be used in a .vilerc if someone needs it.  it
      seemed like the cases we were trying to catch were bugs in other
      programs (shells and window managers).  this seems like the most
      flexible approach, at least until i understand the problems a little
      better.  (x11.c, main.c, cmdtbl, vile.hlp, proto.h)

    + simplified, and moved non_filename() to version.c, so it can more
      easily use the PATCHLEVEL string.  (proto.h, version.c, path.c)

    + changed PATCHLEVEL from a char constant to a string, for more
      flexibility in naming patches.  duh.  (version.c, patchlev.h)

    + added GNU General Public License to distribution, as required by
      configure/configure.in.  (makefile.in, COPYING)

    + tweaked/updated copyrights, added some vile specific caveats and
      info to the COPYING file.

    + reenabled '!' expansion in shell commands.  more vi's than not
      seem to do it.  (input.c)

    + arrange to check the X event queue when doing updates() during
      a pipe read.  we were only checking in x_working() before, which
      isn't called if "set noworking" or OPT_WORKING == FALSE. (proto.h,
      x11.c, file.c)

(tom)
    + modified column shown by ruler to be the actual cursor column, rather
      than the effective column (display.c).

    + made vms sys$/lib$ calls consistent (uppercase) to simplify greps
      (path.c, random.c, termio.c, vms2unix.c, vmspipe.c, vmsvt.c).

    + changed input-buffer size and error checks for vms to avoid
      data overrun problems (termio.c).

    + corrected glob-expansion for environment-variables, e.g., $FOO
      (glob.c).

    + updated tests for memory leaks (bind.c, map.c).

    + corrected glob-expansion of msdos pathnames that use '/' (glob.c).

    + corrected bug that prevented '!' from being inserted into shell
      commands without being escaped (input.c).

    + added command 'append-string' for symmetry with 'insert-string'
      (insert.c, cmdtbl).

    + modified vax scripts to compile on AXP hardware under OpenVMS
      (descrip.mms, display.c, vms_link.opt, vmsbuild.com, vmsshare.opt)

    + corrected shadowing of 'stat' in npopen.c

    + added version.o: patchlev.h dependency to all makefiles.
      (descrip.mms makefile.djg makefile.tbc makefile.wat makefile.wnt)

(kev)
    + main.c (newprocessgroup): Changed XHAVE_SETSID to HAVE_SETSID.
      Added HAVE_BSD_SETPGRP ifdef which is necessary due to the fact
      that setpgrp on BSD systems requires two arguments.

    + x11.c (scroll_selection): Sign extend row and col.  It's possible
      to sign extend in fewer lines of code if we make certain
      assumptions about the widths of ints, shorts, and longs.  Not as
      portable though.

      (extend_selection): Add scrolling timeout _after_ updating the
      display.

    + vile.hlp: did a lot of tweaking/rewording/correcting.

    + display.c (l_to_vcol): Use wp->w_dot instead of DOT.  DOT uses
      curwp which is not what we want here.  This problem was causing
      core dumps when I got into xvile and did the following:

          :help
        /fmt

    + x11.c (x_change_focus): Do not attempt to give ourselves focus
      when focusFollowsMouse is true and we enter the window.  Also,
      don't rely on the receipt of FocusIn/FocusOut events for deciding
      whether or not to show the cursor.

      (x_preparse_args): Set the XtNinput resource to TRUE in the
      call to XtVaAppInitialize() instead of in a separate call to
      XtVaSetValues(). [This is how Volume 4 in the O'Reilly series
      recommends doing it].

      (x_wm_delwin): Removed the unused WM_TAKE_FOCUS stuff from this
      function.

      (grip_moved): Removed superfluous "#if MOTIF_WIDGETS" / "#endif"
      pair.

      (scroll_selection): Cleaned up decoding of row and col.

      (x_preparse_args): Took out WM_TAKE_FOCUS stuff.

This change log started on Wed Jan 11, 1995.
