This was my thought too; but would we be painting ourselves into a
corner if we ever want to make merge-tree support octopus merges?
Also, why did you write $(git merge-base branch^ branch) rather than
just branch^ ?

Yeah, I don't think that'd be too hard...if we could rule out ever
supporting octopus merges in merge-tree (which I'm not so sure is a
good assumption). Otherwise, we might need to figure out the
appropriate backward-compatible input parsing (and output format
changes?)
