+;; | 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

+;; |
+;; | 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)
