From d0f5e7001637062ee21446e986ec528bbf27c621 Mon Sep 17 00:00:00 2001
From: Guido van Rossum <guido@python.org>
Date: Mon, 22 Jan 2001 23:37:04 +0000
Subject: - Use "exec ... in dict" to avoid having to walk on eggshells; locals
   no don't have to start with underscore.

- Add spaces after commas in argument lists.

- Only test dbhash if bsddb can be imported.  (Wonder if there are
  more like this?)
