The main reason for us defining word masking is to support Bath first words
in searches.  If we say that the word masking character is only valid for
right truncation, this will make things a lot simpler.  We could then have a
diagnostic saying "|(word mask character) is in illegal position".  We also
need "| not supported"  Word searching with proximity will accomplish most
of the requirements in a much simpler way.

Yes :)

Yes.  Perhaps some implementations will, and perhaps they won't.  It's
just an unsupported search (though hopefully there's a diagnostic to say
why in particular it's not working)

Yes. It should be zero or more, I think.
