Source Code
;; Defined in /usr/src/emacs/lisp/gnus/gnus-cite.el.gz
;; Some Microsoft products put in a citation that extends to the
;; remainder of the message:
;;
;; -----Original Message-----
;; From: ...
;; To: ...
;; Sent: ... [date, in non-RFC-822-or-later format]
;; Subject: ...
;;
;; Cited message, with no prefixes
;;
;; The four headers are always the same. But note they are prone to
;; folding without additional indentation.
;;
;; Others use "----- Original Message -----" instead, and properly quote
;; the body using "> ". This style is handled without special cases.
