I meant should Emacs automatically turn off fullscreen if you issue a 
frame-size change?  Wouldn't that be appropriate?  If not, maybe the doc for 
each such size-changing function should say explicitly that it has no effect if 
fullscreen is on.  (Maybe it already says that; I haven't checked.)

Dunno.
