I wanted to add the following tests but could not get it to work:

$ cat tests/test-xdg.t
   $ mkdir xdgconf
   $ echo '[ui]' > xdgconf/hgrc
   $ echo 'username = foobar' >> xdgconf/hgrc
   $ XDG_CONFIG_HOME=xdgconf; export XDG_CONFIG_HOME
   $ hg config ui.username
   foobar

I've tried the following:

make PYTHON=python2.7 local
cd tests
python2.7 run-tests.py --local test-xdg.t

But once installed; it works.
