True, but this part

has a subtle issue, which the commit 026351a addresses, which
will hopefully become a non-issue given enough time.  Then it
would be safe to make this change.

Of course, if/when I change the main Makefile to have different
gitexecdir and bindir by default, it would become "my problem",
but until then...

On the other hand, your patch is correct for this part.  The
issue 026351a commit addressed does not apply.  An ancient 'git'
that did not have 'diff-index' (it was called 'diff-cache')
would have hit a breakage early on since 'describe' did not
exist back then.
