Currently there is no need for nested comments, because those are only
single word queries. Or do I not understand what you mean by nested
comments? (There is code for ignore /* .. */ before the first keyword.)

Any suggestion how to that? I can think of a way myself, but it may not be
the best, as I don't consider C my natural language. I can try, or does
anyone else feel inclined to fix this?
