What a human reader would like to understand is whether such a
commit number is recent or not. Therefore, what I would suggest
is to suffix it with a date:
Gnulib 552c0b06355a6720c8ce87ce305f42ed15a32d20 (2024-12-28)
It might also help to put the date first (as that's better for a human
reader) and make it a full timestamp, e.g.:
Gnulib 2024-12-28 19:46:30 +0100 552c0b06355a6720c8ce87ce305f42ed15a32d20
This sort of thing is more robust across version-control systems, and we
found it useful when switching Emacs from bzr to git.
