I've also been able to add q syntax highlighting by adding these two files to /src/resources/pandoc/syntax-definitions/. It looks like you're already storing some Kate syntax files there, so could we add these two as well?

I'm not sure that jives with the agreement that you made me sign in order to contribute, but you're already doing it, so it seems okay?
