From 678d074ba2d20c22255abdcc8c41f3c0e2ec2c2a Mon Sep 17 00:00:00 2001
From: "W. Trevor King" <wking@drexel.edu>
Date: Thu, 23 Jul 2009 10:08:04 -0400
Subject: [PATCH] Added bugdir setting comparision to libbe.diff.

Renamed libbe.diff.diff -> bug_diffs, since it doesn't compare bugdirs.

Load comments before bug comparision so cmp_comments will see them.

Use .settings_properties rather than static lists to create attribute
lists for change_lines().

Removed trailing endline from becommands/diff.py output.
