`save-window-excursion' is the macro never to use.  It should be used
exclusively for debugging and prototyping.  Application programmers who
prefer to work with multiple frames themselves should know best and
avoid `save-window-excursion' like the plague.  At least in "released"
code.  Anything else is masochism.
