evolve: abort if deciding resolution parent is ambiguous
While solving content-divergence, it could be hard to decide
which cset should be treated as a resolution parent if there
are multiple successors of divergent cset. i.e split case.
But we are planning to make some update in handling this split
case:
1) consider highest one if all splitted csets are in a single
topological branch
2) still need to decide if 1) doesn't apply
====================================
Testing head checking code: Case B-7
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category B: simple case involving pruned changesets
TestCase 7: single changesets, pruned then superseeded (on an existing changeset)
