Ember.js/Addon: How do I jshint all javascript files?

I'm writing an ember.js addon. When running ember test Ember will add generic should pass jshint tests to my test suite. That's great as far as it goes, but the javascript files form the main directory (index.js, Brocfile.js) are missing as are the files from app/**/*. As far as I can see, only files in addon/**/\ and tests/**/\ are covered.

Am I missing some obvious configuration option? Is this a bug?
