Exception raised for TODO check

[iwarshak]

First of all, this is very slick. Thanks for doing this. I noticed an error is raised with some of my todos.

Fails:
Repo.preload(:comments)# TODO blah blah

Works:
Repo.preload(:comments) # TODO blah blah

I am pretty sure it is just the lack of space after the # that is causing the issue

Credo: 0.1.4
