This is caused by the C++ magic rule being too vague (m3u files don't have a
magic rule and only get identified by a suffix and if the file has anything like
'//' in it, it gets picked up as a C++ file). 

I was thinking about removing it and the other language magic rules and relying
on suffixes only for these files.
