well, here's where I disagree.  Seeing a screenful at (point) where you
last were in that buffer is pretty useful.  and the problem with the
reverse-video was different because here, the condition was handled
(seemingly) correct, and the whole thing is wrapped in a
save-excursion/save-window-excursion, so I can't see any real cause for
fear except the one about when XEmacs runs out of memory, and has just
enuf to save it's buffers.  That's a scary situation. 

again, I think it's a worthy feature; but I also think that 

(global-set-key [(control R)] 'toggle-read-only) 

is a worthy feature.  I'm not suggesting it b/c I do have some sense of
what should stay `customization' and what should be default behavior.
so maybe the variable `save-some-buffers-query-display-buffer' should be 
nil by default, so that all we've really added is an `if', some extra
overhead in `save-excursion', and a defvar (defcustom) for those who
don't want it.  That sounds good to me.  How people will ever find out
about this variable?  That's a mystery, but at least it's there.
They'll find it if they look hard enuf.
