There's also a global comment_line_char variable, which is closely related (most callers pass it in as this parameter). Let's avoid shadowing the global name. This makes it more obvious that we're not using the global value, and it will be especially helpful as we refactor the global in future patches (in particular, any macro trickery wouldn't work because the preprocessor doesn't respect scope). We'll use "comment_prefix". That should be descriptive enough, and as a bonus is more neutral with respect to the "char" type (since we'll eventually swap it out for a string).
