>> @edvbld What exactly do you propose to test in the unit test? This is really solving a problem with the environment -- the tests fail when I run as my user due to conflicting modifications in my `~/.gitconfig`. I can't really modify the users personal gitconfig file in a unit test. The only thing I could really think if is verifying that `git config -l` is empty. Hm, maybe that's a good idea...

In a CI environment the test will of course be trivially correct since we never setup `user.name`, but the test will be accurate when run on developer's personal machines.

If `user.name` is set, then `git config -l` will not be empty. :)
