next: solve the issue of `next` get confused by split This patch solve a problem of next command which get confused by split. Let me describe how it was getting confused: Initial state of repo: A---B---C After splitting B to (B1,B2): @ A---B1---B2 \ ---B---C X * (note: C is orphan; checkedout to B1) Lets make an amend on B1: @ B1' / A---B1---B2 \ X * \ ---B---C X * Now, if run `hg next` (--evolve is True by default now): $ it would give you choice to choose from B2 and C thinking that C could also be a possbile children for B1, instead of stablizing B2 on B1. I fixed this problem by filtering those aspiring children which can be stablized on one of the aspiring children itself. Changes made in test-prev-next.t shows the changed expected behaviour.
