Hmm, I still find this a little brittle. I think that 'path' here is
doing a number of jobs: it serves as a strmap key, it's visible to the
caller, and now also a "direct object" marker.

Could we instead store this explicitly on the type_and_oid_list, e.g. a
"direct" flag? I'm not sure whether that type has the right scope for
this information. If not, I wonder if there is another way to store this
information, since I worry that future callers may not know about this
convention and end up changing the result of the path-walk depending on
how they name their paths.

Thanks,
Taylor
