good catch!

This seems like pretty confusing wording to me, because i can't tell how
to connect "non-empty" with "excluding" and "optional".  Maybe a
concrete example of what we're trying to fix would also help?  something
like:

    In particular, '[]' and '[^]' are not valid ranges.

I'd be happy if folks can exchange wordsmithing ideas on the list here.

But beyond the wordsmithing, if anyone thinks that Neal's interpretation
(or my proposed clarification) is actually wrong or problematic, please
speak up!
