Feature request: optional sig separator

[Christoph Conrad <christoph.conrad@gmx.de>]

Hello!

See my sig below: it's really all beginning with "Best regards". You
cannot achieve that with Gnus out of the box, cause the sig insertion
code of Gnus always inserts the separator. This should be the default
separator, but it should also possible to turn the insertion of the
default separator off. Maybe THEN should be tested when inserting the
sig if the separator is a valid "^-- $".

To achieve this behaviour i had to do some ugly coding (prevents using
`gnus-posting-styles'):

(setq message-signature-file "~/.signature")
(setq message-signature nil)

;; Calling sequence in function `message-setup':
;; 1) `message-signature-setup-hook'
;; 2) `message-insert-signature'
;;    (not called because message-signature is nil)
;; 3) `message-setup-hook'
(add-hook 'message-signature-setup-hook
          (function
           (lambda()
             "Add sig without extra \"-- \""
             (goto-char (point-max))
             ;; Insert the signature.
             (insert "\n")
             (unless (bolp)
               (insert "\n"))
             (insert-file-contents message-signature-file)
             (goto-char (point-max))
             (or (bolp) (insert "\n")))))

Best regards,
cu, -cc-
