The fix is surprisingly simple, and I think it definitely goes in
the right direction.

Somehow, it bothers me to be forced to view (a_obj, this, from_sha1,
oc) vs (b_obj, next, sha1, oc2) as a sensibly corresponding pair of
tuples, but that is not something your introduction of "oc2"
started, so I won't complain ;-).
