Ugh, right. Names are more than just refnames.

So I think the only way to do this robustly is to ask get_sha1 to
remember more about what happened. We might even be able to get away
without teaching get_sha1_with_context anything else; it already records
the path, so we should be able to just check whether that is non-empty.

But we use an object_array to store the list of objects, and it has no
room for such a bit. So we'd probably want to refactor that, too.
