warning on unary minus/plus

fixed patch, made against vanilla. it will show warning for unary -/+ for
(u)byte and (u)short, but one can silence that with `-(expr)`. it prolly needs
better message with explanation of what it is, and what to do, and why -- but i
leave that for that one who will make a PR out of the patch.
