All touchwin does is disable some optimization, so wnoutrefresh() has to do
more work to figure out what actually changed.  It doesn't actually force
curses to believe that things *did* change.  This is needed because some
things (subwindows?) can cause things to change without telling the right
parts of curses, so wnoutrefresh() doesn't notice.
