prune: work around lazy revset slowdown
Since 3.0 lazy revset is making some revset very slow. We currently work around
the issue by using a simple loop instead.

evolve: write a status message when the working directory changes
Evolve changes the working directory during atop, etc which can confuse people
as they are not aware that this happend. The ideal solution is to not have
evolve change it, however mercurial limitations don't allow us to do that at the
moment. So instead we are printing a status message that the working directory
changed.
