Subject: [PATCH] use perl instead of sed -r to strip colors in test

`sed -r` is not present on some BSD based systems, including MacOSX
Darwin.  perl is standard pretty much everywhere, so this a more
reliable way to test.

Since this is only used for tests, any performance differences
should not matter significantly.
