revlog: do inclusive descendant testing (API) In many other places, a revision is considered a descendant of itself. We update the behavior of `revlog.descendant()` to match this. (for example. `revlog.isancestor` does inclusive testing). No tests break, so it seems safe to do so. This will make it easier to use a more efficient implementation in a later changeset.
