[webkit-dev] Use of -webkit- prefix on CSS Values and Properties

What's the right thing to do for something that is in a CR spec, but the
draft spec for the next version has it behave differently? Specifically, in
Selectors 3, :not only accepts a single simple selector. In Selectors 4, it
accepts a comma separated list of compound selectors (a superset of the
Selectors 3 behavior). See https://bugs.webkit.org/show_bug.cgi?id=56994.

I see three options:
1. Wait until Selectors 4 hits CR before changing :not.
2. Implement :-webkit-not to match Selectors 4 and leave :not matching
Selectors 3.
3. Make :not match Selectors 4.

My preference in this instance is option 3.
