This produces a CAR (Common Ancestor Revision)

Sounds good!
Having a persisting local clone of the MR would make this even more
efficient (less network traffic etc), but we don't need to worry about
that in this context. (That requires some global support from buildbot,
since we probably want to do something similar for all VCS:es)
