  %{
    fin[ish] [frame-number]\tExecute until selected stack frame returns.

If no frame number is given, we run until the currently selected frame
returns.  The currently selected frame starts out the most-recent
frame or 0 if no frame positioning (e.g "up", "down" or "frame") has
been performed. If a frame number is given we run until that frame
returns.
