It's harder in theory, but you might be able to just call
node_distances(self.ancestors, self.descendants,
self.branch.last_patch(), all_descendants(ancestors,
self.branch.last_patch()))

Note that I've deliberately reversed ancestors and descendants here.

We could probably hack that into compact_ancestors/can_skip without too
much trouble.

P.S.  We now have convergence on bzr.integration, bzr.24 and bzr.dev.
Do a "graph-ancestry bzr.24 --merge base bzr.dev", and check out the
orange boxes at just before the merge base!
