evolve --rev reorders the rev to solve instability, trivial case 2 revs wrong order

evolve --rev reorders the rev to solve instability. Harder case, obsolescence
accross three stacks in growing rev numbers.

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)" c1prime c2prime >/dev/null
