That's what I thought.

Err, good point.

Well, just having a basic-infrastructure for highlighting I think is
the first correct step.  If nothing else, people can hind-rewrite
their expressions for scoring for highlighting use.

I wonder if there are any tricky cases other than ^ and $.  I'd have
to think about it, because otherwise those could be easily replaced.
err, no they couldn't as the summary line format is different for
every person.  arg.
