[PATCH 1/3] test-lib.sh: unset XDG_CONFIG_HOME

From: Jeff King <peff@peff.net>
Date: Jul 24, 2012, 11:53 UTC
Message-ID: <20120724115305.GA7328@sigill.intra.peff.net>

Now that git respects XDG_CONFIG_HOME for some lookups, we must be sure to cleanse the test environment. Otherwise, the user's XDG_CONFIG_HOME could influence the test results.

You can test this trivially with:

  XDG_CONFIG_HOME=/whatever ./t1306-xdg-files.sh
