Actually, "diff --no-index" is currently buggy in this regard. In the
followup series to jk/setup-sequence-update (which I mentioned but
haven't posted yet), I teach get_object_dir() not to blindly default to
".git", and found that "diff --no-index" is perfectly happy to look in
".git/objects" for find_unique_abbrev(), even when we know there's no
repository (or it has an unknown vintage).
I fixed it there by just using the default abbrev value for out-of-repo
diffs, and skip calling find_unique_abbrev() at all. That would here,
too.
But if we add object-store initialization at other times, it's a
potential conflict. IMHO this should stay inside find_unique_abbrev(),
where we know we already must look at the object store.
