bug#14166: 24.3.50; report-emacs-bug and mail-user-agent == 'gnus-user-agent

[Michael Heerdegen <michael_heerdegen@web.de>]

Hello,

the problem is the following (with my setup):

- I have an active gnus; currently, I'm having a summary buffer showing
  the emacs-dev newsgroup.  I need it for reference for the composition
  of a bug report.

- I do M-x report-emacs-bug

The result is that the mail composition buffer will have a TO field of
"emacs-devel@gnu.org" instead of "bug-gnu-emacs@gnu.org".
`report-emacs-bug' uses the posting-style of the group I'm currently
reading.  Surprising, and not very useful.


Background: I use mail-user-agent == 'gnus-user-agent.  Not sure if
there are other related settings.

And I have this element in `gnus-posting-styles':

("\\(?:\\(?:g\\(?:\\(?:mane\\|nu\\)\\.emacs\\.devel\\)\\)\\)\\'"
  (TO "emacs-devel@gnu.org")
  (BCC #1="michael_heerdegen@web.de")
  . #2=((FCC nil)))

mainly because I read emacs-devel as a group, but want to reply always
to the mailing list (I know about S L, but I want also to be able to use
the standard reply commands.  Please tell me if that's a bad idea).


I debugged a bit.  Here is what's going on:

M-x report-emacs-bug
--> compose-mail
--> (get mail-user-agent 'composefunc) == 'gnus-msg-mail
--> (gnus-setup-message 'message
	(message-mail to subject other-headers continue
		      nil yank-action send-actions return-action))

The macro `gnus-setup-message' binds `#:group' to the value of
`gnus-newsgroup-name', which is "nntp+Gmane:gmane.emacs.devel" in my
case.

Then it does this:

(add-hook 'message-mode-hook
          (if (memq ,config '(reply-yank reply))
              (lambda ()
                (gnus-configure-posting-styles ,group))
            (lambda ()
              ;; There may be an old " *gnus article copy*" buffer.
              (let (gnus-article-copy)
                (gnus-configure-posting-styles ,group)))))


At the end, running `message-mode-hook' changes the TO field
according to the posting style via `gnus-configure-posting-styles'.


Thanks,

Michael.
