Re: [csswg-drafts] Allow -n in an-b, allow comments within +n and -n

Oh, and note that comments are allowed *anywhere* between two tokens. This is implicit in ["consume a token"](https://drafts.csswg.org/css-syntax/#consume-token) - whenever you ask for the next token, it automatically consumes (and silently discards) any comments as well.  In [Serialization](https://drafts.csswg.org/css-syntax/#serialization), it's specified that impls are *allowed* to remember where comments were, and re-insert them during serialization if they wish, but this information must have no effect on parsing - as far as CSS parsing and grammars are concerned, comments don't exist.
