Subject: [sup-talk] [PATCH] add reply-from hook for user-defined handling of
	default from in replies
In-Reply-To: <1209484583-sup-8823@south>
References: <1209484583-sup-8823@south>
Message-ID: <1213286746-24268-1-git-send-email-marc.hartstein@alum.vassar.edu>

The reply-from hook can now be used to process headers in a different manner
than the default for purposes of generating a default From: header when
replying to an email.
