Recognize keyword-starting identifier correctly #307

Identifiers can start with a keyword, e.g. fortune starts with for. Because IdentPattern did not allow for digits, valid identifiers like auto0 were rejected. A question not addressed by this is that all identifiers starting with __ or _ and uppercase are reserved.
