IIUC redisplay_window respects the window start position specified in
w->start provided w->force_start or w->frozen_window_start_p hold.
Scrolling, recentering, and things like `move-to-window-line' set the
former (frozen_window_start_p seems purely internal).  The question is
whether these should prevail subsequent point movement or, subsequent
point movement should prevail and reset these flags.
