From 0343bff04f62db4adba0e9bb3014fc1e252a064b Mon Sep 17 00:00:00 2001
From: "W. Trevor King" <wking@drexel.edu>

Subject: [PATCH] Improved threaded comment handling.

The previous method only grabbed first line of a comment.  The new
approach replaces the messy Comment->string->parse->html with
Comment->html.

Also replaced all open()s with codecs.open to allow for non-ASCII
output.  Alphabetized the non libbe imports while I was adding codecs.
