Re: `typeset -H' is a bit too thorough

(Still not getting incoming mail here, unfortunately, which means getting
message from the archive and stripping off the HTML.  It would be useful to
be able to get individual messages in plain text, e.g. as an option on the
HTML display.)

The easiest fix is to turn this off whenever the parameter is referred to
by name or by pattern.  I'm not sure if that's the right thing to do with
patterns, but that's always behaved just as if the parameter was picked by
name, so I suppose it's OK.
