Source Code

;; Defined in /usr/src/emacs/lisp/mail/rmail.el.gz
;; Some mailers use "Re(2):" or "Re^2:" or "Re: Re:" or "Re[2]:".
;; This pattern should catch all the common variants.
;; rms: I deleted the change to delete tags in square brackets
;; because they mess up RT tags.
;; Note: this is matched with case-fold-search bound to t.
