Given a revision B and C does it matter if you say "we store B->C" or

Not all deltas are reversible. If the delta B->C says "delete lines
38-57", then that doesn't let you construct the delta C->B. (monotone
stores binary deltas of the xdelta form, I believe, but I think the
same sort of thing can happen in those.)
I see. I guess I was thinking more in the terms of patchfiles and the
lines with "+" or "-" at the beginning. So the question is - are all
deltas in monotone reversible? I remember something about reversing
deltas for the 'update' command when updating working copy to be based
on a different revision before commit...? That revision doesn't need to
be a parent, it can be a sibling...
