Git - v2.43.2

Relative to Git 2.43.1, this release has two important fixes to allow
"git imap-send" to be built with NO_CURL defined, and to restore the
forced flushing behaviour when GIT_FLUSH=1 is set. It also contains
other, unexciting, fixes that have already been merged to the 'master'
branch of the development towards the next major release.

Fixes since Git 2.43.1

• Update to a new feature recently added, "git show-ref --exists".

• Rename detection logic ignored the final line of a file if it is an
  incomplete line.

• "git diff --no-rename A B" did not disable rename detection but did
  not trigger an error from the command line parser.

• "git diff --no-index file1 file2" segfaulted while invoking the
  external diff driver, which has been corrected.

• Rewrite //-comments to / comments / in files whose comments
  prevalently use the latter.

• A failed "git tag -s" did not necessarily result in an error
  depending on the crypto backend, which has been corrected.

• "git stash" sometimes was silent even when it failed due to
  unwritable index file, which has been corrected.

• Recent conversion to allow more than 0/1 in GIT_FLUSH broke the
  mechanism by flipping what yes/no means by mistake, which has been
  corrected.

Also contains documentation updates, code clean-ups and minor fixups.
