Jim,
I've seen you make this suggestion several times. Is there a
canonical or simple way to do that inside the Lexer? Or is the
easiest way to do that to monkey with the stream to ensure it kicks
out a potentially missing character if it isn't the last character
before the EOF?
I've had this problem, and I just had my NL be ('\n'|EOF) and moved
along, for the grammars I had it was 'good enough'. It would seem
much easier, and cleaner to fix up it up as you suggest, just not sure
the cleanest way to go about it.
