The actual values assigned to tokens was inherited from the yacc-based
grammar. With the most recent cleanups, all single-char tokens such as
commas, semis, parens, etc., that get returned from lexer.next simply
as their Unicode values are below utf8.RuneSelf (i.e., 7bit ASCII).
Lower the initial starting value for named token constants accordingly.
