Remove several appearinces of listname in subject

Hi

Several years ago The Bat! was in charge of our mailing lists, but
then we had too many members, and too many lists, and it was no longer
optimal. We then shifted to PHP scripts on the server.

But we're back with The Bat!, and no backup of the lists as they were
set up that time.

So we have a minor problem with the subject line.

We put "[Listname] Subject" in subject, but when someone answers, we get
"[Listname][Listname] Subject" in the subject line.

What's the right reg.expression to remove that, please?
