/*
* Version Changes (and person who did them)
* ------- ---------------------------------
* 3.10 - version that started it all. Found on comp.sources.unix
* Jun88 Volume 15 i037, i038, i039, i040, i042, and INF3
* - Tim Thompson and Tony Andrews
*
* 3.10A - took version of STEVIE posted to usenet and added Amiga
* and BSD support; added undo and redo commands; sped up
* output to screen; sped up on-screen activities (such as
* cursoring); fixed miscellaneous small bugs and changed some
* commands so that they more closely resembled vi.
* - GRWalter (Fred)
*
* 3.11B - added the ability to be run in the background (STEVIE will
* attempt to use the current window, but if it can't then it
* will open its own window). Fixed some other miscellaneous
* bugs (some to do with re-sizing the screen, one to do with
* undo'ing changes on lines that start with whitespace).
* - GRWalter (Fred)
*
* 3.11C - fixed a bug that was causing the entire screen to be refreshed
* at the wrong times sometimes. Input mode was sped up as well
* as a bug involving lines that wrapped was fixed. Changed :ta
* a bit. Fixed bug triggered when files are > 6000 lines.
* - GRWalter (Fred)
*
* 3.31A - Tony Andrews put out a divergent version of STEVIE (version 3.31).
* I moved the important stuff over into my version.
*
* Here is a list of what was moved over :
*
*************************************************************************
* Revision 3.29 88/06/26 14:53:19 tony
* Added support for a simple form of the "global" command. It supports
* commands of the form "g/pat/d" or "g/pat/p", to delete or print lines
* that match the given pattern. A range spec may be used to limit the
* lines to be searched.
*
* Revision 3.28 88/06/25 21:44:22 tony
* Fixed a problem in the processing of colon commands that caused
* substitutions of patterns containing white space to fail.
*
* Revision 3.26 88/06/10 13:44:06 tony
* Fixed a bug involving writing out files with long pathnames. A small
* fixed size buffer was being used. The space for the backup file name
* is now allocated dynamically.
*
* Revision 1.12 88/05/03 14:39:52 tony
* Also merged in support for DOS.
*
* Revision 1.11 88/05/02 21:38:21 tony
* The code that reads files now handles boundary/error conditions much
* better, and generates status/error messages that are compatible with
* the real vi. Also fixed a bug in repeated reverse searches that got
* inserted in the recent changes to search.c.
*
* Revision 1.10 88/05/02 07:35:41 tony
* Fixed a bug in the routine plines() that was introduced during changes
* made for the last version.
*
* Revision 1.9 88/05/01 20:10:19 tony
* Fixed some problems with auto-indent, and added support for the "number"
* parameter.
*
* Revision 1.8 88/04/30 20:00:49 tony
* Added support for the auto-indent feature.
*
* Revision 1.6 88/04/28 08:19:35 tony
* Modified Henry Spencer's regular expression library to support new
* features that couldn't be done easily with the existing interface.
* This code is now a direct part of the editor source code. The editor
* now supports the "ignorecase" parameter, and multiple substitutions
* per line, as in "1,$s/foo/bar/g".
*
* Revision 1.5 88/04/24 21:38:00 tony
* Added preliminary support for the substitute command. Full range specs.
* are supported, but only a single substitution is allowed on each line.
*
* Revision 1.4 88/04/23 20:41:01 tony
* Worked around a problem with adding lines to the end of the buffer when
* the cursor is at the bottom of the screen (in misccmds.c). Also fixed a
* bug that caused reverse searches from the start of the file to bomb.
*
* Revision 1.3 88/03/24 08:57:00 tony
* Fixed a bug in cmdline() that had to do with backspacing out of colon
* commands or searches. Searches were okay, but colon commands backed out
* one backspace too early.
*
* Revision 1.2 88/03/21 16:47:55 tony
* Fixed a bug in renum() causing problems with large files (>6400 lines).
*************************************************************************
* - GRWalter (Fred)
*
* 3.32A - added the :[range]d command. Played with 'p' and 'P'.
* Added undo capability to :s and :g//d commands.
* Added '%' as a line range specifier (entire file).
* Fixed search so that tags file from real ctags could be used.
* Fixed undo after delete everything operation.
* Made prt_line work in nu mode (so :g//p works right).
* Fixed ai mode (when there was text after the cursor it didn't ai).
* Fixed 'J' (didn't handle next line just having whitespace).
* Fixed :[range] so it behaves like the real vi (goes to highest
* line number in the given range).
* Made it so that the cursor is on the last char inserted instead
* the one right after when there is exactly 1 char right after.
* Made change operator work properly when it ended on the
* end of the line.
* - GRWalter (Fred)
*
* 3.33A - no longer updateNextscreen when putting or undoing or
* redoing until I am done. 'p', 'u' and '.' thus sped up.
* - no longer recalculate line lengths when cursupdate() called,
* which speeds up lots'a things (like on-screen cursoring).
* - avoid redrawing (in updateNextscreen) as much as possible, which
* speeds up (among other things) cursoring (off screen), put, undo,
* redo, etc.
* - GRWalter (Fred)
*
* 3.34A - rewrote updateNextscreen and updatenextline so they won't do as
* much work. Sped up cursoring off-screen. Fixed bug in cursupdate
* (could index through NULL pointer).
* - GRWalter (Fred)
*
* 3.35A - Compiles with Lattice 5.0 now - needed miscellaneous changes.
* - Environment variables (EXINIT) finally used.
* - Stevie is now compiled so it's residentable.
* - Fixed bug in insstr() (caused problems with redo of inserts).
* - Fixed buffer overflow/corrupt messages.
* - Tweaked updateNextscreen routine some more.
* - Added __DATE__ and __TIME__ of compilation to help screen.
* - GRWalter (Fred)
