patch, showing no regression. As I have no suggestions on code changes
any more, can I commit your version directly?

I think it'd be good to at least add a comment to the new block
explaining what it's doing (I'm happy to leave that up to you if you
want). But other than that I've looked it over again and am reasonably
happy.

Cheers.

Tim.
