Unable to delete "References:" lines

Unable to delete "References:" lines

[Lloyd Zusman]

I'm writing about something I first noticed in the CVS of ognus several
months ago, and that I have kept forgetting to mention here until now.

I don't keep much of an address book on line, and if I want to send an
email to someone to whom I've corresponded before, I often will just
take a copy of an old message from that person, respond to it via
`gnus-summary-reply-{wide-}with-original', change the subject, delete
the "References:" line, and continue with my new message to him or her.

But what I've been noticing over the past few months is that when I send
the outgoing message, the deleted "References:" line reappears.  I
assume that this was done for a good reason, probably to help maintain
the integrity of message threads, but in cases such as these, I'd like
to disable this behavior and send the message out with no "References:"
header at all.

Is there a variable or hook which controls this behavior?

Thanks in advance.

One more detail: in the case I mentioned below, the exact behavior is
this: I see the deleted "References:" line reappear if I save the
message (C-x C-s) before sending.  I therefore believe that this
behavior has something to do with saving drafts.

Hi,

By a similar reason, I also feel it is inconvenient that I can't
edit the References header.  Then I use the following hook:

(add-hook
 'message-setup-hook
 (lambda nil
   ;; Generate the References header and clear the corresponding
   ;; elements in the `message-reply-headers' buffer-local variable.
   (let ((references (message-make-references))
	 reference)
     (if references
	 (progn
	   (mail-header-set-message-id message-reply-headers nil)
	   (mail-header-set-references message-reply-headers nil)
	   (setq references (split-string references))
	   (goto-char (point-min))
	   (insert "References: ")
	   (while references
	     (setq reference (car references)
		   references (cdr references))
	     (if (> (+ (current-column) (length reference)) 78)
		 (progn
		   (delete-char -1)
		   (insert "\n ")))
	     (insert reference (if references
				   " "
				 "\n")))
	   (message-sort-headers))))))

Thank you for this (and I apologize for not replying sooner).

I presume this works because deleting the existing references causes
Gnus to assume that there are none to preserve, correct?

Exactly.  You can edit them (for example, delete except the last ID)
and can also delete the header whole.

I understand.  And I find it interesting that the message ID also has to
be removed, or else this doesn't seem to work.

Yeah, I complained about this when the change was made.

The solution is to make the References and/or In-Reply-To headers
empty, e.g., change

  References: <m365iv537b.fsf@asfast.com>

to

  References:

in your draft.

It's a bit difficult to determine what the user wants, really.  For
instance, if the user removes the From header, a new one has to be
generated, and is probably what the user wants.  If the user removes
the References header, the user probably doesn't want to have the
header re-generated.

Perhaps the fix would be to not re-generate the optional headers if
they are removed?

I've now done so.

Yes, that works.  Thank you (and I'm sorry for taking so long to reply).
