Author: wmorgan <wmorgan@5c8cc53c-5e98-4d25-b20a-d8db53a31250>
Date:   Sun, 10 Dec 2006 19:11:40 +0000

improved handling of killing buffers. buffers now check with the mode
(via #killable?) before killing. inbox-mode always returns false.

also improved ask_yes_or_no. three outputs: yes, no, and nil (cancel).
