[Rivet] Branched release-2-0

Thanks! 'hg graft' is the right tool in that situation, but it's a hack,
as we've got two nodes in the revision tree now that are identical. It
breaks the theoretical "one changeset for one purpose" idea, with
implications for 'hg bisect' etc.

But I've had to use it myself many times, too! :-)
