Another thing we could do is split the commit date into two fields, and
make the top one extremely readable. E.g.
date: 7:04:49 p.m. Sat May 20 2006

Yeah, I'd prefer to be very consistent, at least when there's a chance
of it being read by a person.

You see the conflict resolution, plus all changes originated by the
committer up to that point.

H+I is essentially unrelated to the E-M branch. If E-M is a branch of
TreeTransform work, H+I is a branch locking fix, three new commands, a
new repository format, Twisted, and some documentation updates. It's
not something you'd ever want to review when looking at E-M.
Here's a worse case:
~ \ \ \ \
In the E-O branch, nothing has changed. We've just got a bunch of
merges. If you go with leftmost parents, then F is B+C+D, G is H+I+J
and O is K+L+M. This isn't an unusual case. It tends to happen to my

Well, we'll have deterministic merges once you integrate that fix for
the Patience SequenceMatcher. :-) But I agree, we don't want to prevent
future merge improvements.

Yeah, that might be nice.
