Thank you Kevin,

my intention is to show the local path, so the test is wrong as you
said. Thanks for reviewing the patch and pointing this out. I've now
been able to run the tests on my PC and I got a new version of the
patch that uses Matt Harbison's suggestion of using "subrelpath(self)"
rather than "self._path" and also fixes the test. I'll resend the
patch shortly.

Thank you both for your comments,

Angel
