Some minor fixes

* Few minor improvements
* Could you confirm that commit #b6ec661 address a leftover?

BTW I was think about adding a rule to check that the args name
is not conflicting with clojure.core functions, what do you think?
(based on ` (->> aFunction var meta :arglists)`)
This `(-> no-docstrings count pos?)` shouldn't be removed, because it's being used as the return value for this function
