Subject: [PATCH 2/2] emacs: make modifications to message Fcc vars
 buffer-local
Date: Sat,  1 Aug 2015 11:44:56 +0200
Message-Id: <1438422296-29087-3-git-send-email-david@tethera.net>

Precedence: list

Previously we globally modified these variables, which tended to cause
problems for people using message-mode, but not notmuch-mua-mail, to
send mail.

User visible changes:

- calling notmuch-fcc-header-setup is no longer optional. OTOH, it
  seems to do the right thing if notmuch-fcc-dirs is set to nil.

- the Fcc header is visible during message composition

- the name in the mode line is changed, and (sadface) no longer
  matches the menu label.

- Previously notmuch-mua-send-and-exit was never called.  Either we
  misunderstood define-mail-user-agent, or it had a bug.  So there was
  no difference if the user called message-send-and-exit directly. Now
  there will be.
