    dtc: Trivial lexer cleanups
    
    This patch applies a couple of tiny cleanups to the lexer.  The
    not-very-useful 'WS' named pattern is removed, and the debugging
    printf() for single character tokens is moved to the top of the
    action, which results in less confusing output when LEXDEBUG is
    switched on (because it goes before the printf()s for possible
    resulting lexer state changes).
