for push, it's a bit different. If a range is specified (instead of a
list of revs), then they should be connected (no "holes" in the ranges).

We'd need some way to specify interesting topological orderings too, I
guess.

Being able to mix queries with other repos, would be interesting too
(e.g. only match from outgoing csets).
