From d0259ae0e1a37f431b21c8a7116b4206c127f8b6 Mon Sep 17 00:00:00 2001
From: Steven Knight <knight@baldmt.com>
Date: Mon, 29 Dec 2008 07:24:44 +0000
Subject: Update to latest Test{Cmd,Common}.py, including fixes for working
 with other modules that use atexit, a zip() in earlier Python versions that
 don't have it built in, and better error message reported when we can't
 compile a regular expression.
