added functionality - it.only, jshint, console.log

It does not seem to come up that much - far less than coffeelint warnings - so I do not think it is too bad.

However, the amount of errors in a run through of this in agents is concerning - would probably take a morning of work just to get agents passing all tests (Lots of whitespace at end of line, ++ operators, tab indentation, empty param lists). Maybe if it is a git repo only new code should be considered.
