Subject: [PATCH 6/9] emacs: Add unified refresh-this-buffer function
Date: Thu, 29 Aug 2013 12:25:54 -0400
Message-Id: <1377793557-28878-7-git-send-email-amdragon@mit.edu>
In-Reply-To: <1377793557-28878-1-git-send-email-amdragon@mit.edu>
References: <1377793557-28878-1-git-send-email-amdragon@mit.edu>
Precedence: list

This unifies the various refresh and poll-and-refresh functions we
have for different modes.  Now all modes bind "=" and "G" (except
show, which doesn't bind "G" for some reason) to
`notmuch-refresh-this-buffer' and
`notmuch-poll-and-refresh-this-buffer', respectively.
