MSYS在windows下模拟了一个类unix的终端

  This means there is a swap file, which can be used for recovery.

Tags:
- Included ctags 2.0 (Darren Hiebert).  The syntax for static tags changed
  from
	{tag}:{fname}	{fname}	{command}
  to
	{tag}	{fname}	{command};"	file:
  Which is both faster to parse, shorter and Vi compatible.  The old format is
  also still accepted, unless disabled in src/feature.h (see OLD_STATIC_TAGS).
  |tags-file-format|
- Completion of tags now also includes static tags for other files, at the
  end.
- Included "shtags" from Stephen Riehm.
- When finding a matching tag, but the file doesn't exist, continue searching
  for another match.  Helps when using the same tags file (with links) for
  different versions of source code.
- Give a tag with a global match in the current file a higher priority than a
  global match in another file.

Included xxd version V1.8 (Juergen Weigert).

Autocommands:
- VimLeave autocommands are executed after writing the viminfo file, instead
  of before.  |VimLeave|
- Allow changing autocommands while executing them.  This allows for
  self-modifying autocommands. (idea from Goldberg)
- When using autocommands with two or more patterns, could not split
  ":if/:endif" over two lines.  Now all matching autocommands are executed in
  one do_cmdline().
- Autocommands no longer change the command repeated with ".".
- Search patterns are restored after executing autocommands.  This avoids
  that the 'hlsearch' highlighting is messed up by autocommands.
- When trying to execute an autocommand, also try matching the pattern with
  the short file name.  Helps when short file name is different from full
  file name (expanded symbolic links). |autocmd-patterns|
- Made the output of ":autocmd" shorter and look better.
- Expand <sfile> in an ":autocmd" when it is defined.  |<sfile>|
- Added "nested" flag to ":autocmd", allows nesting.  |autocmd-nested|
- Added [group] argument to ":autocmd".  Overrides the currently set group.
  |autocmd-groups|
- new events:
  |BufUnload|		before a buffer is unloaded
  |BufDelete|		before a buffer is deleted from the buffer list
  |FileChangedShell|	when a file's modification time has changed after
			executing a shell command
  |User|		user-defined autocommand
- When 'modified' was set by a BufRead* autocommand, it was reset again
  afterwards.  Now the ":set modified" is remembered.

GUI:
- Improved GUI scrollbar handling when redrawing is slower than the scrollbar
  events are generated.
- "vim -u NONE" now also stops loading the .gvimrc and other GUI inits.  |-u|
  Use "-U" to use another gvimrc file.  |-U|
- Handle CTRL-C for external command, also for systems where "setsid()" is
  supported.
- When starting the GUI, restrict the window size to the screen size.
- The default menus are read from $VIMRUNTIME/menu.vim.  This allows for a
  customized default menu.  |menu.vim|
- Improved the default menus.  Added File/Print, a Window menu, Syntax menu,
  etc.
- Added priority to the ":menu" command.  Now each menu can be put in a place
  where you want it, independent of the order in which the menus are defined.
  |menu-priority|

Give a warning in the intro screen when running the Win32 console version on
Windows 95 because there are problems using this version under Windows 95.
|win32-problems|

Added 'e' flag for ":substitute" command: Don't complain when not finding a
match (Campbell).  |:s|

When using search commands in a mapping, only the last one is kept in the
history.  Avoids that the history is trashed by long mappings.

Ignore characters after "ex", "view" and "gvim" when checking startup mode.
Allows the use of "gvim5" et. al.  |gvim| "gview" starts the GUI in readonly
mode.  |gview|

When resizing windows, the cursor is kept in the same relative position, if
possible.  (Webb)

":all" and ":ball" no longer close and then open a window for the same buffer.
Avoids losing options, jumplist, and other info.

"-f" command-line argument is now ignored if Vim was compiled without GUI.
|-f|

In Visual block mode, the right mouse button picks up the nearest corner.

Changed default mappings for DOS et al.  Removed the DOS-specific mappings,
only use the Windows ones.  Added Shift-Insert, Ctrl-Insert, Ctrl-Del and
Shift-Del.

Changed the numbers in the output of ":jumps", so you can see where {count}
CTRL-O takes you.  |:jumps|

Using "~" for $HOME now works for all systems.  |$HOME|

Unix: Besides using CTRL-C, also use the INTR character from the tty settings.
Somebody has INTR set to DEL.

Allow a <LF> in a ":help" command argument to end the help command, so another
command can follow.

Doing "%" on a line that starts with "   #if" didn't jump to matching "#else".
Don't recognize "#if", "#else" etc. for '%' when 'cpo' contains the '%' flag.
|%|

Insert mode expansion with "CTRL-N", "CTRL-P" and "CTRL-X" improved
|ins-completion|:
- 'complete' option added.
- When 'nowrapscan' is set, and no match found, report the searched direction
  in the error message.
- Repeating CTRL-X commands adds following words/lines after the match.
- When adding-expansions, accept single character matches.
- Made repeated CTRL-X CTRL-N not break undo, and "." repeats the whole
  insertion.  Also fixes not being able to backspace over a word that has been
  inserted with CTRL-N.

When copying characters in Insert mode from previous/next line, with CTRL-E or
CTRL-Y, 'textwidth' is no longer used.  |i_CTRL-E|

Commands that move in the arglist, like ":n" and ":rew", keep the old cursor
position of the file (this is mostly Vi compatible).

Vim now remembers the '< and '> marks for each buffer.  This fixes a problem
that a line-delete in one buffer invalidated the '< and '> marks in another
buffer.  |'<|

For MSDOS, Unix and OS/2: When $VIM not set, use the path from the executable.
When using the executable path for $VIM, remove "src/" when present.  Should
make Vim find the docs and syntax files when it is run directly after
compiling.  |$VIM|

When quitting Visual mode with <Esc>, the cursor is put at start of the Visual
area (like after executing an operator).

Win32 and Unix version: Removed 1100 character limit on external commands.

Added possibility to include a space in a ":edit +command" argument, by
putting a backslash before it.  |+cmd|

After recovery, BufReadPost autocommands are applied.  |:recover|

Added color support for "os2ansi", OS/2 console. (Slootman) |os2ansi|

Allow "%:p:h" when % is empty.  |:_%|

Included "<sfile>": file name from the ":source" command.  |<sfile>|

Added "<Bslash>" special character.  Helps for avoiding multiple backslashes
in mappings and menus.

In a help window, a double-click jumps to the tag under the cursor (like
CTRL-]).

<C-Left> and <C-Right> now work like <S-Left> and <S-Right>, move a word
forward/backward (Windows compatible). |<C-Left>|

Removed the requirement for a ":version" command in a .vimrc file.  It wasn't
used for anything.  You can use ":if" to handle differences between versions.
|:version|

For MS-DOS, Win32 and OS/2: When comparing file names for autocommands, don't
make a difference between '/' and '\' for path separator.

New termcap options:
"mb": blink.  Can only be used by assigning it to one of the other highlight
      options.  |t_mb|
"bc": backspace character.  |t_bc|
"nd": Used for moving the cursor right in the GUI, to avoid removing one line
      of pixels from the last bold character.  |t_nd|
"xs": highlighting not erased by overwriting, for hpterm.  Combined with
      'weirdinvert'.  Visual mode works on hpterm now.  |t_xs|

Unix: Set time of patch and backup file same as original file.  (Hiebert).

Amiga: In QuickFix mode no longer opens another window.  Shell commands can be
used now.

Added decmouse patches from David Binette.  Can now use Dec and Netterm mouse.
But only when enabled at compile time.

Added '#' register: Alternate file name |quote#|.  Display '#' register with
":dis" command. |:display|

Removed ':' from 'isfname' default for Unix.  Check for "://" in a file name
anyway.  Also check for ":\\", for MS-DOS.

Added count to "K"eyword command, when 'keywordprg' is "man", is inserted in
the man command.  "2K" results in "!man 2 <cword>".  |K|

When using "gf" on a relative path name, remove "../" from the file name, like
it's done for file names in the tags file. |gf|

When finishing recording, don't make the recorded register the default put
register.

When using "!!", don't put ":5,5!" on the command-line, but ":.!".  And some
other enhancements to replace the line number with "." or "$" when possible.

MSDOS et al.: Renamed $VIM/viminfo to $VIM/_viminfo.  It's more consistent:
.vimrc/_vimrc and .viminfo/_viminfo

For systems where case doesn't matter in file names (MSDOS, Amiga), ignore
case while sorting file names.  For buffer names too.

When reading from stdin doesn't work, read from stderr (helps for "foo | xargs
vim").

32 bit MS-DOS version: Replaced csdpmi3 by csdpmi4.

Changed <C-Left> and <C-Right> to skip a WORD instead of a word.

Warning for changed modified time when overwriting a file now also works on
other systems than Unix.

Unix: Changed the defaults for configure to be the same as the defaults for
Makefile: include GUI, Perl, and Python.

Some versions of Motif require "-lXpm".  Added check for this in configure.

Don't add "-L/usr/lib" to the link line, causes problems on a few systems.

==============================================================================
			     COMPILE TIME CHANGES	*compile-changes*

When compiling, allow a choice for minimal, normal or maximal features in an
easy way, by changing a single line in src/feature.h.
The DOS16 version has been compiled with minimal features to avoid running
out of memory too quickly. |dos16|
The Win32, DJGPP, and OS/2 versions use maximal features, because they have
enough memory.
The Amiga version is available with normal and maximal features.

Added "make test" to Unix version Makefile.  Allows for a quick check if most
"normal" commands work properly.  Also tests a few specific commands.

Added setlocale() with codepage support for DJGPP version.

autoconf:
- Added autoconf check for -lXdmcp.
- Included check for -lXmu, no longer needed to edit the Makefile for this.
- Switched to autoconf 2.12.
- Added configure check for <poll.h>.  Seems to be needed when including
  Perl on Linux?
- termlib is now checked before termcap.
- Added configure check for strncasecmp(), stricmp() and strnicmp().  Added
  vim_stricmp() for when there's no library function for stricmp().
- Use "datadir" in configure, instead of our own check for HELPDIR.

Removed "make proto" from Makefile.manx.  Could not make it work without a lot
of #ifdefs.

Removed "proto/" from paths in proto.h.  Needed for the Mac port.

Drastically changed Makefile.mint.  Now it includes the Unix Makefile.

Added support for Dos16 in Makefile.b32 (renamed Makefile.b32 to Makefile.bor)

All source files are now edited with a tabstop of 8 instead of 4, which is
better when debugging and using other tools.  'softtabstop' is set to 4, to
make editing easier.

Unix: Added "link.sh" script, which removes a few unnecessary libraries from
the link command.

Don't use HPUX digraphs by default, but only when HPUX_DIGRAPHS is defined.
|digraphs-default|

==============================================================================
				 BUG FIXES		*bug-fixes*

Note:	Some of these fixes may only apply to test versions which were
	created after version 4.6, but before 5.0.


When doing ":bdel", try going to the next loaded buffer.  Don't rewind to the
start of the buffer list.

mch_isdir() for Unix returned TRUE for "" on some systems.

Win32: 'shell' set to "mksnt/sh.exe" breaks ":!" commands.  Don't use
backslashes in the temp file names.

On linux, with a FAT file system, could get spurious "file xxx changed since
editing started" messages, because the time is rounded off to two seconds
unexpectedly.

Crash in GUI, when selecting a word (double click) and then extend until an
empty line.

For systems where isdigit() can't handle characters > 255, get_number() caused
a crash when moving the mouse during the prompt for recovery.

In Insert mode, "CTRL-O P" left the cursor on the last inserted character.
Now the cursor is left after the last putted character.

When quickfix found an error type other than 'e' or 'w', it was never printed.

A setting for 'errorfile' in a .vimrc overruled the "-q errorfile" argument.

Some systems create a file when generating a temp file name.  Filtering would
then create a backup file for this, which was never deleted.  Now no backup
file is made when filtering.

simplify_filename() could remove a ".." after a link, resulting in the wrong
file name.  Made simplify_filename also work for MSDOS.  Don't use it for
Amiga, since it doesn't have "../".

otherfile() was unreliable when using links.  Could think that reading/writing
was for a different file, when it was the same.

Pasting with mouse in Replace mode didn't replace anything.

Window height computed wrong when resizing a window with an autocommand (could
cause a crash).

":s!foo!bar!" wasn't possible (Vi compatible).

do_bang() freed memory twice when called recursively, because of autocommands
(test11).  Thanks to Electric Fence!

"v$d" on an empty line didn't remove the "-- VISUAL --" mode message from the
command-line, and inverted the cursor.

":mkexrc" didn't check for failure to open the file, causing a crash.
(Felderhoff).

Win32 mch_write() wrote past fixed buffer, causing terminal keys no longer to
be recognized.  Both console and GUI version.

Athena GUI: Crash when removing a menu item.  Now Vim doesn't crash, but the
reversing of the menu item is still wrong.

Always reset 'list' option for the help window.

When 'scrolloff' is non-zero, a 'showmatch' could cause the shown match to be
in the wrong line and the window to be scrolled (Acevedo).

After ":set all&", 'lines' and 'ttytype' were still non-default, because the
defaults never got set.  Now the defaults for 'lines' and 'columns' are set
after detecting the window size. 'term' and 'ttytype' defaults are set when
detecting the terminal type.

For (most) non-Unix systems, don't add file names with illegal characters when
expanding.  Fixes "cannot open swapfile" error when doing ":e *.burp", when
there is no match.
