It has been a while since I looked at that code. But when Jelmer removed
revision_history I remember him having some helper code for the transition.
It really doesnt scale well to use it, because it requires walking all the

I would try to look at using the graph objects to find unique ancestors on
I can give you a few more direct pointers if you are interested.
