Hi Mike

Unfortunately as you are using regex a lot, you are going to be finding a
lot of these errors.

Fortunately I have a solution, but it is a fairly big change so will
have to wait for the weekend.

The error is just showing the part of the expression that it could not
handle, so nothing has been really lost.  I'll see if I can get the
original rule printed or at least change the message to show that it
is just a part of the original rule.
