From f63ba43733aca984272540040d43ddf0c3fbdae9 Mon Sep 17 00:00:00 2001
From: Raymond Hettinger <python@rcn.com>

Subject: * Dynamically build a list of files to be tested (necessary because  
 version 2.39 of dectest.zip adds some new test files and because   some
 existing test files were getting skipped). * Remove two docstrings which
 cluttered unittest's output. * Simplify a for-loop with a list comprehension.
