Uncaught Error: Parsing error at undefined: Please check the validity of the CSS block starting from the line #5

[alem0lars]

Steps to reproduce

1. I tried to execute "CssComb: Run" in the following file:

@charset "utf-8";

// Apply styles for the page approach.
@mixin apply-page-approach($ns) {
  html##{$ns} > body.approach {
  }
}

And I got the error below.

Atom Version: 0.177.0 System: Mac OS X 10.10.2 Thrown From: csscomb package, v0.1.2

This seems to be an issue with how CSScomb is handling the parsing. If you don't mind creating an issue over there that would be great!
