/*
* Vim originated from Stevie version 3.6 (Fish disk 217) by GRWalter (Fred)
* It has been changed beyond recognition since then.
*
* All the remarks about older versions have been removed, they are not very
* interesting. Differences between version 3.0 and 4.0 can be found in
* "../doc/vim_40.txt".
*
* Changes between version 4.1 and 4.2:
* - Included ctags version 1.3.
* - Included xxd.c version 1.4 (only one change since 1.3m)
* - Unix: Adjusted check for child finished again. Now use != ECHILD
* instead of == EINTR.
* - Fixed: loading compressed files (with autocommands) didn't work when
* 'textmode' was previously set.
* - Fixed: When executing a shell, a window resize was not recognized for
* Unix.
* - Fixed: For GUI, when executing an external command, a window resize
* caused the buffer to be redrawn.
* - Fixed: Error message for not being able to open the .viminfo file could
* report the wrong filename.
* - MS-DOS, Win32, OS/2: When $HOME is not set, use "C:/".
* - OS/2: Improved handling of wildcards again. Didn't ignore case, didn't
* work with backslashes.
* - Fixed: ":s/pat<Tab>" could cause a core dump or other problems.
* - Fixed: When entering a hidden buffer with ":e", the BufEnter autocommands
* were not executed.
* - Fixed: Ignoring a CTRL-Z at end-of-file was only done on MS-DOS. Now it
* also works on other systems, but only in textmode.
* - Fixed: In the GUI special characters were not passed on to external
* commands, typeahead was truncated.
* - Added "gq" as an alias to "Q". Should be used when "Q" is made to be Vi
* compatible: go to Ex mode.
* - Fixed: "gu" in Visual mode could not be redone with "." correctly.
* - Fixed: ":normal" command made any typeahead executed right away, causing
* unpredictable problems.
* - Fixed: ":normal atest^[" didn't update the screen.
* - Fixed: Redoing blockwise visual delete at the end of the file could cause
* "invalid line number" errors.
* - Fixed: vim_rename() didn't open the output file in binary mode, could
* cause the .viminfo file to contain CR-LF on OS/2.
* - Fixed: OS/2 was using /tmp/xxx for temporary file name, would fail if
* there is no /tmp directory. Now use $TMP/xxx, defaulting to c:/ if $TMP
* is not set.
* - Fixed: When USE_TMPNAM was defined, was using the wrong array size for
* the viminfo temporary file.
*
* Changes between version 4.0 and 4.1:
*
* - Included xxd.c version 1.3m.
* - Included ctags version 1.2.
* - Included tools/efm_filt.er.
* - Included changes for port to Atari MiNT, including makefile.mint.
* - Included a few changes for OS/2: Improved executing external commands,
* depending on the shell; Handle resize after executing an external
* command; Handle wildcard expansion for more than one argument (e.g.
* ":n *.c *.h").
* - Include a lot of small changes to the docs.
* - Fixed: GUI version would busy-loop and mappings didn't work. Was caused
* by gui_mch_wait_for_chars() not working properly. This fix was the main
* reason for releasing 4.1.
* - Fixed: setting 'term' while GUI is active was possible, and caused
* problems.
* - Fixed: When the "to" part of a mapping or menu command was long (more
* than 24 chars on 32 bit MS-DOS, 128 chars on other systems), any <> were
* not translated and CTRL-Vs not removed.
* - Fixed: 'modified' option was included for ":mkvimrc", it shouldn't.
* - Included a few changes for that Atari MiNT port (vt52 builtin term
* entry).
* - Fixed: on MS-DOS a file name pattern for an autocommand that contains
* "\*" or "\?" didn't work.
* - On MS-DOS and Amiga, ignore case when matching the file name pattern for
* autocommands.
* - Fixed: using :set to show the value of two options gave an error message
* (e.g. ":set so sj").
* - Fixed: Non-printable characters in a file name caused trouble when
* displayed in a status line.
* - Pack the MS-DOS zip files with Infozip, under Unix. Preserves the long
* filenames and case. Files with two dots don't work though, the first dot
* is replaced with an underscore.
* - Fixed: Pasting more than one line with the mouse in insert mode, didn't
* put the cursor after the last pasted character.
* - When pasting linewise text, put the '] mark on the last character of the
* last line, instead of the first character of the last line.
* - Fixed: on some Unix systems, when resizing the window while in a external
* command (e.g., ":!cat"), Vim would stop waiting for the child, causing
* trouble, because the child is still running.
* - Fixed: resizing the window while executing an external command, and
* 't_ti' and 't_te' are defined to swap display buffers, Vim would redraw
* in the wrong display buffer after the "hit RETURN" message.
* - Fixed: "va", "vA", "Vp", "VP", "Vs" and "VS" didn't set the cursor
* position used for up/down movements (e.g., when using "j" after them).
* - Fixed: in GUI version, after using "cw" visual selection by dragging the
* mouse didn't work.
* - Fixed: setting 'ttyscroll' to 0 caused scrolling of message to stop
* working.
* - Fixed: the "WARNING: file changed" message caused buffers to be flushed
* and subsequent commands not to be executed.
* - Fixed: in Insert mode, the message from "^O^G" would be
* overwritten by the mode message if 'showmode' set.
* - Fixed: Using ":bdel" when there is only one buffer with two windows,
* could cause a crash.
* - Changed: the '<' flag in 'cpoptions' now only switches off the
* recognizing of the <> form of key codes. The 'k' flag is now used for
* the recognizing of raw key codes.
* - Fixed: Typing ':' at the --more-- prompt, when displaying autocommands,
* caused extra linefeeds to be produced.
* - Fixed: Using 'tagrelative' and ":set tags=./../tags", filenames would
* contain "../" as many times as CTRL-] would be used. These are removed
* now.
* - Fixed: Extremely long error message could cause a crash (e.g., when
* using ":help ^A<CR>").
* - Added check for negative value of 'textwidth'.
* - Fixed: On MS-DOS, getting the value of $HOME would cause the current
* directory for the drive to be changed.
