Commit 38a4556 (index-pack: start learning to emulate
"verify-pack -v", 2011-06-03) added a "delta_depth" counter
to each "struct object_entry". Initially, all object entries
have their depth set to 0; in resolve_delta, we then set the
depth of each delta to "base + 1". Base entries never have
their depth touched, and remain at 0.

This patch causes index-pack to fail on the pack that triggered the
whole discussion.  More in a minute in another side thread, but
meanwhile: NAK until we understand what is really going on here.

Odd; that's what I was testing with, and it worked fine.

Let me double-check that I didn't screw up my tests. I initially did
something more like:

  if (is_delta_type(base->obj->type))
          delta_obj->delta_depth = base->obj->delta_depth + 1;
  else
          delta_obj->delta_depth = 1;

and I'm wondering if I screwed up testing the revised version.
