Realized better what is bothering me about this proposal.
The proposal says:
1. A single asterisk (*) is used to mask zero or more characters.
4. A single vertical bar (|) is used to mask zero or more words.
Question is how is a*b different from a|b
I believe the answer (if I understand correctly) is it has nothing
to do with the masked characters - it implies that "a" and "b" must
be "words" -- that is there must be a "word boundary" before and
after both "a" and "b".
An alternative interpretation is that "a & b" matches a*b but
not a|b because "&" is not a word - if you mean that this will be hard.
If my first interpretation is correct that will require explaining -
I won't start a debate (though am tempted) about whether it is good.
