.. and this one are unfortunate as the rest of the object store series
has not progressed as far as needed.

The lookup_commit series is out there already, and that will
teach lookup_commit a repository argument. When rerolling
that series I need to switch the order of repo_init and lookup_commit
such that we can pass the repo to the lookup.

This is really nice!

Overall this series looks good to me,
