Splitting one window should not involve destroying all Lisp references to
existing windows (as `save-window-excursion' must).  Unless redisplay
would somehow be supressed here (I'm not sure), this would also involve
calling `window-size-change-functions' twice for each split, which would
be wasteful and perhaps confusing.
