Git 2.51.2 Release Notes
========================

In addition to fixes for an unfortunate regression introduced in Git
2.51.1 that caused "git diff --quiet -w" to be not so quiet when there
are additions, deletions and conflicts, this maintenance release merges
more fixes/improvements that have landed on the master front, primarily
to make the CI part of the system a bit more robust.


Fixes since Git 2.51.1
----------------------

 * Recently we attempted to improve "git diff -w --quiet" and friends
   to handle cases where patch output would be suppressed, but it
   introduced a bug that emits unnecessary output, which has been
   corrected.

 * The code to squelch output from "git diff -w --name-status"
   etc. for paths that "git diff -w -p" would have stayed silent
   leaked output from dry-run patch generation, which has been
   corrected.

 * Windows "real-time monitoring" interferes with the execution of
   tests and affects negatively in both correctness and performance,
   which has been disabled in Gitlab CI.

 * An earlier addition to "git diff --no-index A B" to limit the
   output with pathspec after the two directories misbehaved when
   these directories were given with a trailing slash, which has been
   corrected.

 * The "--short" option of "git status" that meant output for humans
   and "-z" option to show NUL delimited output format did not mix
   well, and colored some but not all things.  The command has been
   updated to color all elements consistently in such a case.

 * Unicode width table update.

 * Recent OpenSSH creates the Unix domain socket to communicate with
   ssh-agent under $HOME instead of /tmp, which causes our test to
   fail doe to overly long pathname in our test environment, which has
   been worked around by using "ssh-agent -T".

Also contains various documentation updates, code cleanups and minor fixups.
