f7ac313629 - mark actual EBNF with pre-formatted class "ebnf" instead of "grammar" 
- make real productions for Unicode char classes so that they can be parsed
- use `` for tokens that contain "'s or \'s so that they can be parsed
- added a missing '.'

This version of the spec passes through ebnflint (forthcoming) without errors.
