Evolve --rev more complex case: two sets of stacks one with prune an no successor, the other one

partially solvable

First set of stack:

  $ mkstack "desc(_d)" c1_ c2_ c3_ c4_ >/dev/null

  $ mkstack "desc(_d)" c1prime c2prime >/dev/null

  $ mkstack "desc(_d)" c1second >/dev/null

  $ hg prune "desc(c1_)" -s "desc(c1prime)"

  1 changesets pruned

  3 new unstable changesets

  $ hg prune "desc(c2_)" -s "desc(c2prime)"

  1 changesets pruned

  $ hg prune "desc(c1prime)" -s "desc(c1second)"

  1 changesets pruned
