`"chuck item"` results in trailing comma in clojure

[AndreasArvidsson]

          This one is unfortunately quite hard. If the comment wasn't there the comma would be cleaned up. The whole thing about dealing with comments is something I intend to do in the future, but for now I think we will have to make due with this implementation.
