From 8d3d05c7cb81611537aa34fa68e98e5e22b74847 Mon Sep 17 00:00:00 2001
From: Dan McGee <dan@archlinux.org>
Date: Tue, 15 Feb 2011 20:00:33 -0600
Subject: Allow for optional info in required by display

We need to make our root object the PackageDepend rather than the Package to
get at this, so do a slight refactor on get_requiredby().
