patch 9.1.0049: Make "[Command Line]" a special buffer name Commit: https://github.com/vim/vim/commit/1fb41032060df09ca2640dc49541f11062f6dfaa Author: Sean Dewar <seandewar@users.noreply.github.com> Date: Wed Aug 16 17:15:05 2023 +0100 patch 9.1.0049: Make "[Command Line]" a special buffer name Problem: E95 is possible if a buffer called "[Command Line]" already exists when opening the cmdwin. This can also happen if the cmdwin's buffer could not be deleted when closing. Solution: Un-name the cmdwin buffer, and give it a special name instead, similar to what's done for quickfix buffers and for unnamed prompt and scratch buffers. As a result, BufFilePre/Post are no longer fired when opening the cmdwin. Add a "command" key to the dictionary returned by getbufinfo() to differentiate the cmdwin buffer instead. (Sean Dewar) NOTE: This is technically a breaking change... maybe this needs a different solution? (Or maybe this issue can be ignored...) A GitHub search reveals some plugins expect the old behaviour. However, many of those plugins also do not seem to account for the string being translated, so they are subtly broken anyway (not withstanding the fact that you can call any old buffer "[Command Line]" too...) closes: #12819 Signed-off-by: Sean Dewar <seandewar@users.noreply.github.com> Signed-off-by: Christian Brabandt <cb@256bit.org>

The files in this directory come from the xdiff implementation in git.
You can find it here: https://github.com/git/git/tree/master/xdiff
The files were last updated March 17, 2023 from git release v.2.40.0

This is originally based on libxdiff, which can be found here:
http://www.xmailserver.org/xdiff-lib.html

The git version was used because it has been maintained and improved.
And since it's part of git it is expected to be reliable.

The code is distributed under the GNU LGPL license.  It is included in the
COPYING file.

Changes in these files were made to avoid compiler warnings.

The /* */ comments are kept to make syncing to a newer version easier, do not
change them to // comments!

The first work for including xdiff in Vim was done by Christian Brabandt.
