  I thought about that, but `scmutil.rev*()` would have to return new filtered `repo`
  object, which didn't seem nice. And mutating a given `repo` argument has the
  original problem, when to discard unhidden revisions. So my conclusion was a
  separate function.

  Doesn't each command know whether it should unhide or not?
