If the selected window changes for any reason, redisplaying the
previously selected window will be queued by select_window:

  if (NILP (norecord) || EQ (norecord, Qmark_for_redisplay))
    { /* Mark the window for redisplay since the selected-window has
	 a different mode-line.  */
      wset_redisplay (XWINDOW (selected_window)); 
      wset_redisplay (w);
    }
  else
    redisplay_other_windows ();
