hbisect.get: use simpler code with repo.set(), fix 'pruned' set
Use repo.set() wherever possible, instead of locally trying to
reproduce complex graph computations.
'pruned' now means 'all csets that will no longer be visited by the
bisection'. The change is done is this very patch instead of its own
dedicated one becasue the code changes all over the place, and the
previous 'pruned' code was totally rewritten by the cleanup, so it
was easier to just change the behavior at the same time.
The previous series went in too fast for this cleanup pass to be
included, so here it is. ;-)
