It is not. It's a left over from when I was trying to match GNU output format. I've fixed it now.

Any thoughts on testing the json output? Repeating all of the expectations for json output is rather.. repetitive, and it doesn't really ensure the output is valid json. Is there any way to assert that the output parses as json?
