Subject: [ANNOUNCE] Git v2.38.2

The latest maintenance release Git v2.38.2 is now available at the
usual places.  There is nothing exciting here, it mostly is to
backport/backmerge the accumulated fixes, including GitHub CI
integration, made during 2.39 development cycle to the 2.38
maintenance track.

The tarballs are found at:

    https://www.kernel.org/pub/software/scm/git/

The following public repositories all have a copy of the 'v2.38.2'
tag and the 'maint' branch that the tag points at:

Git 2.38.2 Release Notes
========================

This is to backport various fixes accumulated during the development
towards Git 2.39, the next feature release.


Fixes since v2.38.1
-------------------

 * Update CodingGuidelines to clarify what features to use and avoid
   in C99.

 * The codepath that reads from the index v4 had unaligned memory
   accesses, which has been corrected.

 * "git remote rename" failed to rename a remote without fetch
   refspec, which has been corrected.

 * "git clone" did not like to see the "--bare" and the "--origin"
   options used together without a good reason.

 * Fix messages incorrectly marked for translation.

 * "git fsck" failed to release contents of tree objects already used
   from the memory, which has been fixed.

 * "git rebase -i" can mistakenly attempt to apply a fixup to a commit
   itself, which has been corrected.

 * In read-only repositories, "git merge-tree" tried to come up with a
   merge result tree object, which it failed (which is not wrong) and
   led to a segfault (which is bad), which has been corrected.

 * Force C locale while running tests around httpd to make sure we can
   find expected error messages in the log.

 * Fix a logic in "mailinfo -b" that miscomputed the length of a
   substring, which lead to an out-of-bounds access.

 * The codepath to sign learned to report errors when it fails to read
   from "ssh-keygen".

 * "GIT_EDITOR=: git branch --edit-description" resulted in failure,
   which has been corrected.

 * Documentation on various Boolean GIT_* environment variables have
   been clarified.

 * "git multi-pack-index repack/expire" used to repack unreachable
   cruft into a new pack, which have been corrected.

 * The code to clean temporary object directories (used for
   quarantine) tried to remove them inside its signal handler, which
   was a no-no.

 * "git branch --edit-description" on an unborh branch misleadingly
   said that no such branch exists, which has been corrected.

 * GitHub CI settings have been adjusted to recent reality, merging
   and cherry-picking necessary topics that have been prepared for Git
   2.39.

 * `git rebase --update-refs` would delete references when all `update-ref`
   commands in the sequencer were removed, which has been corrected.

Also contains various documentation updates and code clean-ups.
