Are we 100% sure this part is necessary? From my understanding of the
problem, even without any ambiguity get_oid() could fail due to just
plain not finding the object in question.

We have get_oid_commit() and get_oid_committish() already. Should rebase
just be using those? (I think we probably want "commit()", because we do
not expect a "pick" line to have a tag, for example.
