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).
