I don't know if is a bug or if I don't know use `hoc` correctly. When I call `$ hoc` I got: ``` $ hoc fatal: bad revision ''--author='' 0 ``` If I use: ``` $ hoc --author="Fabricio Cabral" fatal: bad revision ''--author=Fabricio' 0 ``` I got the same message. So, Is it's a bug or a usage mistake? If it's a usage mistake, could you improve the docs?
