I'd be happy to get rid of it. It doesn't add any real capabilities to the notation,
and it's nice to have a warning-free grammar.

So... if someone *wants* ". $" notation, please speak up ASAP.
Otherwise, I'll just remove it soon.

But this expedition *did* end up pointing out a grammar problem, namely,
that we weren't supporting scomments after period.  So it was still worthwhile.
