Fix comment bug

Browse Source 
There is a bug in processing the comments in source files. It's
related to #326. And this bug comes out when you comment something
with the character ';', and include the quotation mark without its
pair in it.

The lastest version of rgbds compiler has a step to parse the given
source to convert its line endings to a unified one, and it
processes quotation marks even before it processes the comments.

I edited a little bit of the source, and it works fine now.
