Problems with lwarn at startup

Problems with lwarn at startup

[Lennart Borgman]

If I add the code below to my .emacs and answer 'n' the splash screen 
does not go away. It changes form however to some text only form.

  (unless (y-or-n-p "Some question ")
    (lwarn '(test) :warning "Test warning"))

This is important to debug, since we're talking about using lwarn
during startup.  Would someone please fix it and ack?

When Lennart answers "n", lwarn splits the frame into two windows
(using the lower one for the warning). startup.el contains a function
`use-fancy-splash-screens-p' which decides whether to use "fancy"
(graphic) or "normal" (text) splash screen according to several
criteria, among them the following:

 (> window-height (+ image-height 19))

If you try starting Emacs with the following .emacs.el:

;;;;;;;;;;;;;;;;; .emacs.el ;;;;;;;;;;;;;;;;;
(defun use-fancy-splash-screens-p () t)
(unless (y-or-n-p "Some question ")
   (lwarn '(test) :warning "Test warning"))
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

you won't see the "bug".

Maybe use frame-height instead of window-height?

I think the intention is precisely *not* to show the fancy splash
screen in too small a window...

Yes, of course, but showing another splash screen just because of a 
warning makes it looks like everything could be wrong. It disturbs the 
users view and make the warning disappear from his/her perception I believe.

And it seems like Richard agrees with you ;-)

I did that.  Thanks.
