Subject: (rmail-output): If message was shown with full headers,
X-Git-Tag: emacs-19.34~11015
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=49e4a58a708bb23541188a5a5a3df4ec8509b457;p=emacs.git

(rmail-output): If message was shown with full headers,
copy the full headers (or each message copied) into the file.
New local var original-headers-p, header-beginning, mail-from.
Bind locals outside the while loop.  Kill tembuf only after loop.
If message has a saved mail-from field, use that.
Detect reaching end of rmail buffer; display # messages copied.
