Tried that already - however the subsequent htmlificaton then goes on to
convert the html link I put in the subject by escaping all the < and >
charaters - aagh!

I've come to the conclusion that what I want isn't that sensible anyway - I
can just create a resource variable with the html link in it and then stick
that on the generated pages as normal.

What might be more generally useful is a way of overriding the 'sort by
subject' function - for example in my case I could look in the subject for a
bugid, so that mails would sort as I require even if the bugid wasn't the
first word in the subject.
