No such command.  See `ispell-command-loop'.  Of course, one could
advise ispell-command-loop itself to propagate ispell-quit (which is
going to be reset to nil later) to, e.g., ispell-quit-pos.

Is it possible to do advising "locally" (like let()ting), so it is
automatically undone when the calling function exits?
