-;; Two silly functions to ensure that all `y-or-n-p' questions clear
-;; the echo area.
-;;
-;; Do we really need these functions? Workarounds for bugs in the corresponding
-;; Emacs functions? Maybe these bugs are no longer present in any supported
-;; (X)Emacs version? Alias them to the original functions and see if anyone
-;; reports a problem. If not, replace with original functions. --rsteib,
-;; 2007-12-14
-;;
-;; All supported Emacsen clear the echo area after `yes-or-no-p', so we can
-;; remove `yes-or-no-p'. RMS says that not clearing after `y-or-n-p' is
-;; intentional (see below), so we could remove `gnus-y-or-n-p' too.
-;; Objections? --rsteib, 2008-02-16

-;; | The behavior of `y-or-n-p' that it doesn't clear the question
-;; | and the answer is not serious of course, but I feel it is not
-;; | cool.
-;; |
-;; | It is intentional.
-;; |
-;; | Currently, it is commented out in the trunk by Reiner Steib. He
-;; | also wrote the benefit of leaving the question and the answer in
-;; | the echo area as follows:
-;; |
-;; | (http://article.gmane.org/gmane.emacs.gnus.general/66061)

-;; | > SPC, DEL, etc accidentally, so it might be useful for the user
-;; | > to see what he has typed.

-;; | Yes, that is the reason.
