From c487b847e2053b13c4eea0ccfeecf5a41c396412 Mon Sep 17 00:00:00 2001
From: Joey Hess <joey@kodama.kitenet.net>
Date: Mon, 7 Jan 2008 16:34:13 -0500
Subject: * Improved the canedit hook interface, allowing a callback function
 to be   returned (and not run in some cases) rather than the plugins directly
   forcing a user to log in. * opendiscussion: allow editing of the toplevel
 discussion page,   and, indirectly, allow creating new discussion pages.
