See switch-to-new-untitled-buffer in
http://lists.gnu.org/archive/html/gnu-emacs-sources/2008-09/msg00016.html

Here is the Commentary:

;; The switch-to-new-buffer command is like switch-to-buffer, but it
;; generates a new buffer name instead of prompting the user.  It sets
;; buffer-offer-save to protect against inadvertant data loss via
;; kill-emacs.  And it adds a buffer-local query function to protect
;; against inadvertant data loss via kill-buffer.
;;
;; switch-to-new-scratch-buffer and switch-to-new-untitled buffer are
;; convenience commands, for creating new *scratch* buffers (like Emacs)
;; and new "Untitled" buffers (like other text editors).
;;
;; switch-to-new-buffer is added to the menu bar Buffers menu.
