From e41d00bb6a503023ee1fe95bfb8ffe9a53b22ca9 Mon Sep 17 00:00:00 2001
From: Guido van Rossum <guido@python.org>

Subject: Fixed a bug: files that no longer exist remotely would never be
 removed from .mirrorinfo.  Now they are (even if -r is not specified -- the
 files are not removed, just their .mirrorinfo entry).

Added a feature: the -s pattern option is also used to skip local
files when removing (i.e. -r won't remove local files matching the -s
patterns).
