Make pop_most_recent_commit() return the same objects multiple times, but only
if called with different bits to mark.
This is necessary to make merge-base work again.

The old implementation was a nice algorithm, but, unfortunately, it could
be confused in some cases and would not necessarily do the obvious thing
if one argument was decended from the other. This version fixes that by
changing the criterion to the most recent common ancestor.

This switches to my implementation of merge-base, but with the new parsing
library.

Also, make it a fatal error to pass in a non-commit object. The callers
never checked, so better check here.
This simplifies merge-base further. It's now so trivial that it's almost
ridiculous.
parent of two commits.
The question of "best" commit can probably be tweaked almost arbitrarily.
In particular, trying to take things like how big the tree differences
are into account migt be a good idea. This one is just very simple.
