You may not need the path name, but instead the hash value that
pack-objects computes from the path name.  All that matters is
the hash, so pack-objects can schedule the objects into the right
buckets when its doing delta computation for objects which are not
yet delta compressed, or whose delta cannot be suitably reused.
