better not have a non-header line after Subject

better not have a non-header line after Subject

[Dan Jacobson]

Both plain emacs 22 or "No gnus", send differently mangled mail when given

Subject: bla, and
a second non header line starting in column 1

Garbage in, garbage out, but not caught.

There is code in mail-send to detect that:

	;; Complain about any invalid line.
	(goto-char (point-min))
	(while (< (point) (mail-header-end))
	  (unless (looking-at "[ \t]\\|.*:\\|$")
	    (push-mark opoint)
	    (error "Invalid header line (maybe a continuation line lacks 
initial whitespace)"))
	  (forward-line 1))

But mail-header-end seems to be broken: it calls rfc822-goto-eoh instead
of searching for the mail-header-separator (either the text on a line by
itself or the category text property value).

That's how continuation lines work...

	(goto-char (point-min))
	(while (< (point) (mail-header-end))
	  (unless (looking-at "[ \t]\\|.*:\\|$")

I checked in the required fix to sendmail.el.  Thanks.

(I think message-mode needs to be fixed too; CC'ing ding@gnus.org).

Thanks.  Gnus checks for continuation header lines only when
posting news articles.  I've made it do so for mail messages as
well in the Gnus CVS repository.  The changes will be merged to
the Emacs CVS after a while.

(As for blank header lines, Gnus removes them silently using
`message-cleanup-headers'.)

I've made a minor change in docstring of `message-syntax-checks'
and updated the Mesage Info manual (both trunk and v5-10 branch).
