It will be something like:

(defcustom message-yank-prefix
  (if (featurep 'xemacs)
      "> "
    (if (or (string-match "\\`23\\.1\\.5[0-9]\\.[0-9]*\\'" emacs-version)
	    (>= emacs-major-version 24)
	    (and (= emacs-major-version 23) (>= emacs-minor-version 2)))
	mail-yank-prefix
      "> "))
  "doc string")

But I don't find a meaningful difference in it from:

(defcustom message-yank-prefix "> "
  "doc string")

In other words, I'd prefer to revert the recent changes in message.el.
