MSYS在windows下模拟了一个类unix的终端

key code possible.  This makes the termcode translations and mappings more
consistent.  Now all modifiers work in all combinations, not only with <Tab>,
but also with <Space>, <CR>, etc.

For Unix, restore three more signals.  And Vim catches SIGINT now, so CTRL-C
in Ex mode doesn't make Vim exit.

""a5Y" yanked 25 lines instead of 5.

"vrxxx<Esc>" in an empty line could not be undone.

A CTRL-C that breaks ":make" caused the errorfile not to be read (annoying
when you want to handle what ":make" produced so far).

":0;/pat" didn't find "pat" in line 1.

Search for "/test/s+1" at first char of file gave bottom-top message, or
didn't work at all with 'nowrapscan'.

Bug in viminfo history.  Could cause a crash on exit.

":print" didn't put cursor on first non-blank in line.

":0r !cat </dev/null" left cursor in line zero, with very strange effects.

With 'showcmd' set and 'timeoutlen' set to a few seconds, trick to position
the cursor leftwards didn't work.

AIX stty settings were restored to cs5 instead of cs8 (Winn).

File name completion didn't work for "zsh" versions that put spaces between
file names, instead of NULs.

Changed "XawChain*" to "XtChain*", should work for more systems.

Included quite a few fixes for rightleft mode (Lottem).

Didn't ask to |hit-return| when GUI is started and error messages are printed.

When trying to edit a file in a non-existent directory, ended up with editing
"No file".

"gqap" to format a paragraph did too much redrawing.

When 'hlsearch' set, only the current window was updated for a new search
pattern.

Sometimes error messages on startup didn't cause a |hit-return| prompt,
because of autocommands containing an empty line.

Was possible to select part of the window in the border, below the command
line.

'< and '> marks were not at the correct position after linewise Visual
selection.

When translating a help argument to "CTRL-x", prepend or append a '_', when
applicable.

Blockwise visual mode wasn't correct when moving vertically over a special
character (displayed as two screen characters).

Renamed "struct option" to "struct vimoption" to avoid name clash with GNU
getopt().

":abclear" didn't work (but ":iabclear" and ":cabclear" did work).

When 'nowrap' used, screen wasn't always updated correctly.

"vim -c split file" displayed extra lines.

After starting the GUI, searched the termcap for a "gui" term.

When 'hls' used, search for "^$" caused a hang.
When 'hls' was set, an error in the last regexp caused trouble.

Unix: Only output an extra <EOL> on exit when outputted something in the
alternate screen, or when there is a message that needs to be cleared.

"/a\{" did strange things, depending on previous search.

"c}" only redrew one line (with -u NONE).

For mappings, CTRL-META-A was shown as <M-^A> instead of <MC-A>, while :map
only accepts <MC-A>.  Now <M-C-A> is shown.

Unix: When using full path name in a tags file, which contains a link, and
'hidden' set and jumping to a tag in the current file, would get bogus
ATTENTION message.  Solved by always expanding file names, even when starting
with '/'.

'hlsearch' highlighting of special characters (e.g., a TAB) didn't highlight
the whole thing.

"r<CR>" didn't work correctly on the last char of a line.

sometimes a window resize or other signal caused an endless loop, involving
set_winsize().

"vim -r" didn't work, it would just hang (using tgetent() while 'term' is
empty).

"gk" while 'nowrap' set moved two lines up.

When windows are split, a message that causes a scroll-up messed up one of the
windows, which required a CTRL-L to be typed.

Possible endless loop when using shell command in the GUI.

Menus defined in the .vimrc were removed when GUI started.

Crash when pasting with the mouse in insert mode.

Crash whith ":unmenu *" in .gvimrc for Athena.

"5>>" shifted 5 lines 5 times, instead of 1 time.

CTRL-C when getting a prompt in ":global" didn't interrupt.

When 'so' is non-zero, and moving the scrollbar completely to the bottom,
there was a lot of flashing.

GUI: Scrollbar ident must be long for DEC Alpha.

Some functions called vim_regcomp() without setting reg_magic, which could
lead to unpredictable magicness.

Crash when clicking around the status line, could get a selection with a
backwards range.

When deleting more than one line characterwise, the last character wasn't
deleted.

GUI: Status line could be overwritten when moving the scrollbar quickly (or
when 'wd' is non-zero).

An ESC at the end of a ":normal" command caused a wait for a terminal code to
finish.  Now, a terminal code is not recognized when its start comes from a
mapping or ":normal" command.

Included patches from Robert Webb for GUI.  Layout of the windows is now done
inside Vim, instead of letting the layout manager do this.  Makes Vim work
with Lesstif!

UMR warning in set_expand_context().

Memory leak: b_winlnum list was never freed.

Removed TIOCLSET/TIOCLGET code from os_unix.c.  Was changing some of the
terminal settings, and looked like it wasn't doing anything good.  (suggested
by Juergen Weigert).

Ruler overwrote "is a directory" message.  When starting up, and 'cmdheight'
set to > 1, first message could still be in the last line.

Removed prototype for putenv() from proto.h, it's already in osdef2.h.in.

In replace mode, when moving the cursor and then backspacing, wrong characters
were inserted.

Win32 GUI was checking for a CTRL-C too often, making it slow.

Removed mappings for MS-DOS that were already covered by commands.

When visually selecting all lines in a file, cursor at last line, then "J".
Gave ml_get errors.  Was a problem with scrolling down during redrawing.

When doing a linewise operator, and then an operator with a mouse click, it
was also linewise, instead of characterwise.

When 'list' is set, the column of the ruler was wrong.

Spurious error message for "/\(b\+\)*".

When visually selected many lines, message from ":w file" disappeared when
redrawing the screen.

":set <M-b>=^[b", then insert "^[b", waited for another character.  And then
inserted "<M-b>" instead of the real <M-b> character.  Was trying to insert
K_SPECIAL x NUL.

CTRL-W ] didn't use count to set window height.

GUI: "-font" command-line argument didn't override 'guifont' setting from
.gvimrc. (Acevedo)

GUI: clipboard wasn't used for "*y".  And some more Win32/X11 differences
fixed for the clipboard (Webb).

Jumping from one help file to another help file, with 'compatible' set,
removed the 'help' flag from the buffer.

File-writable bit could be reset when using ":w!" for a readonly file.

There was a wait for CTRL-O n in Insert mode, because the search pattern was
shown.
Reduced wait, to allow reading a message, from 10 to 3 seconds.  It seemed
nothing was happening.

":recover" found same swap file twice.

GUI: "*yy only worked the second time (when pasting to an xterm)."

DJGPP version (dos32): The system flags were cleared.

Dos32 version: Underscores were sometimes replaced with y-umlaut (Levin).

Version 4.1 of ncurses can't handle tputs("", ..).  Avoid calling tputs() with
an empty string.

<S-Tab> in the command-line worked like CTRL-P when no completion started yet.
Now it does completion, last match first.

Unix: Could get annoying "can't write viminfo" message after doing "su".  Now
the viminfo file is overwritten, and the user set back to the original one.

":set term=builtin_gui" started the GUI in a wrong way.  Now it's not
allowed anymore.  But "vim -T gui" does start the GUI correctly now.

GUI: Triple click after a line only put last char in selection, when it is a
single character word.

When the window is bigger than the screen, the scrolling up of messages was
wrong (e.g. ":vers", ":hi").  Also when the bottom part of the window was
obscured by another window.

When using a wrong option only an error message is printed, to avoid that the
usage information makes it scroll off the screen.

When exiting because of not being able to read from stdin, didn't preserve the
swap files properly.

Visual selecting all chars in more than one line, then hit "x" didn't leave an
empty line.  For one line it did leave an empty line.

Message for which autocommand is executing messed up file write message (for
FileWritePost event).

"vim -h" included "-U" even when GUI is not available, and "-l" when lisp is
not available.

Crash for ":he <C-A>" (command-line longer than screen).

":s/this/that/gc", type "y" two times, then undo, did reset the modified
option, even though the file is still modified.

Empty lines in a tags file caused a ":tag" to be aborted.

When hitting 'q' at the more prompt for ":menu", still scrolled a few lines.

In an xterm that uses the bold trick a single row of characters could remain
after an erased bold character.  Now erase one extra char after the bold char,
like for the GUI.

":pop!" didn't work.

When the reading a buffer was interrupted, ":w" should not be able to
overwrite the file, ":w!" is required.

":cf%" caused a crash.

":gui longfilename", when forking is enabled, could leave part of the
longfilename at the shell prompt.

==============================================================================
VERSION 5.1						*version-5.1*

Improvements made between version 5.0 and 5.1.

This was mostly a bug-fix release, not many new features.


Changed							*changed-5.1*
-------

The expand() function now separates file names with <NL> instead of a space.
This avoids problems for file names with embedded spaces.  To get the old
result, use substitute(expand(foo), "\n", " ", "g").

For Insert-expanding dictionaries allow a backslash to be used for
wildchars.  Allows expanding "ze\kra", when 'isk' includes a backslash.

New icon for the Win32 GUI.

":tag", ":tselect" etc. only use the argument as a regexp when it starts
with '/'.  Avoids that ":tag xx~" gives an error message: "No previous sub.
regexp".  Also, when the :tag argument contained wildcard characters, it was
not Vi compatible.
When using '/', the argument is taken literally too, with a higher priority,
so it's found before wildcard matches.
Only when the '/' is used are matches with different case found, even though
'ignorecase' isn't set.
Changed "g^]" to only do ":tselect" when there is more than on matching tag.

Changed some of the default colors, because they were not very readable on a
dark background.

A character offset to a search pattern can move the cursor to the next or
previous line.  Also fixes that "/pattern/e+2" got stuck on "pattern" at the
end of a line.

Double-clicks in the status line do no longer start Visual mode.  Dragging a
status line no longer stops Visual mode.

Perl interface: Buffers() and Windows() now use more logical arguments, like
they are used in the rest of Vim (Moore).

Init '" mark to the first character of the first line.  Makes it possible to
use '" in an autocommand without getting an error message.


Added							*added-5.1*
-----

"shell_error" internal variable: result of last shell command.

":echohl" command: Set highlighting for ":echo".

'S' flag in 'highlight' and StatusLineNC highlight group: highlighting for
status line of not-current window.  Default is to use bold for current
window.

Added buffer_name() and buffer_number() functions (Aaron).
Added flags argument "g" to substitute() function (Aaron).
Added winheight() function.

Win32: When an external command starts with "start ", no console is opened
for it (Aaron).

Win32 console: Use termcap codes for bold/reverse based on the current
console attributes.

Configure check for "strip". (Napier)

CTRL-R CTRL-R x in Insert mode: Insert the contents of a register literally,
instead of as typed.

Made a few "No match" error messages more informative by adding the pattern
that didn't match.

"make install" now also copies the macro files.

tools/tcltags, a shell script to generate a tags file from a TCL file.

"--with-tlib" setting for configure.  Easy way to use termlib: "./configure
--with-tlib=termlib".

'u' flag in 'cino' for setting the
