- ;; (autoload 'mu-cite/cite-original "mu-cite" nil t)
- ;; ;; for all but message-mode
- ;; (add-hook 'mail-citation-hook 'mu-cite/cite-original)
- ;; ;; for message-mode only
- ;; (setq message-cite-function (function mu-cite/cite-original))
- ;; for EMACS 18
- ;; ;; for all but mh-e
- ;; (add-hook 'mail-yank-hooks (function mu-cite/cite-original))
