I am not sure which browsers this affects, but I know this is an issue on Chrome 28 Beta. Chrome doesn't run scripts properly when linking to files on raw.github.com. They get served as plain text, I assume to prevent people from linking to them to reduce server load. Obviously, this doesn't break it in all browsers, but maybe some. I can only confirm on Chrome 28 beta.
