Hard restore with X drops staged pins at every depth

X restores the selection to the committed pins without the staged or
committed question, and resets every restored repository's index to
HEAD, so staged pins below are dropped too. Dropped staged pins alone
don't make it ask; they are listed if something else is lost.
