I forgot checking `yes-or-no-p'.  I verified that it clears a
question by itself with Emscs 20.7-23.0.60 and XEmacs 21.4/21.5.

(defun fooo ()
  "Switch to buffer named fooo."
  (interactive)
  (when (yes-or-no-p "Switch to buffer fooo? ")
    (switch-to-buffer "fooo")))

I don't know why `gnus-yes-or-no-p' was introduced, but it might
have been for Emacs 19 because it appeared in "(ding) Gnus v0.30"
(I no longer have Emacs 19 and cannot verify it).  Anyway, I
believe we don't need `gnus-yes-or-no-p'

OTOH, I also checked `y-or-n-p' again with all the versions of
Emacsen and confirmed it doesn't clear a question.  So, I strongly
oppose to making `gnus-y-or-n-p' alias to `y-or-n-p' or removing
`gnus-y-or-n-p'.
