The ref_paranoia code gets pushed down into do_for_each_ref_oid, but it
needs called in both do_for_each_ref variants. This is probably an
artifact of rebasing the patches (the ref_paranoia stuff was added
recently).
I think it would make sense to pull the setup of the data struct into a
shared function rather than duplicate it. But we want to avoid having to
update do_for_each_ref callsites, so we'll have to provide a wrapper.
Like this:

You can even dispense with the _oid variant wrapper, and just call into
the generic version directly from the new callsites.
