can't format comment

[vinurs]

have the code like this

(defn test
  []
;; this is a comment
  (+
   1 2))

but the comment line can not be formatted, it shows All source files formatted correctly

I'd be okay with a PR that makes formatting comments optional, though I don't think it should be the default. Comments aren't code, and shouldn't necessarily have the same indentation.

There is some good discussion on formatting comments in this existing issue: #112
