Absolutely.  We would want to make sure that the new code does not
interfere with established uses when the user does not ask for the
new feature (i.e. XDG not set), and also make sure it does what it
was meant to do when the feature is called for (i.e. XDG set).  It
might be true that the set of tests in the series did not test the
full spectrum of the latter, but then we would want to see the gap
filled by adding missing tests, not by converting tests for former
into the ones that test for the latter.

Even with the patch below there may be other gaps in the test. For
example, core.excludesfile and core.attributesfile must default to
the XDG location when they exist, whether these variables are set;
we may want to make sure that is not broken in the future.

Michael, could you change the direction of the patch and look into
filling such gaps?
