I looked through this patch, and the conversion looks faithful and
straightforward to me. Just two minor comments:

I noticed that you used update_ref_oid() in other places of this
patch. Perhaps this should use update_ref_oid() as well for
consistency?

Ah, I just noticed that this is a very poorly named variable. Whoops.
Since we are here, should we rename this to something like "old_oid"?
Also, this should probably be a "const struct object_id *" as well, I
think.
