I think `make-directory-autoloads' would be even easier, but it was
introduced with 28.1, and we currently support 27.1, sigh!  I think I
can solve it with the patch below.

@Uwe: Can you please apply this to a clean main branch and run make?
This change contains what Stefan sent, but I don't think it can take
care of your Mercurial setup, try it in a real Git repo.  It should at
least cater for your Emacs version.  Thanks.

Best, Arash
