Shaun,
Please resubmit this patch (and all subsequent patches) as attached files. I attempted saving your mail (which has the patch part in BASE64) and converting it using a base64 utility. The patch is malformed, probably due to added line breaks for longer lines. That's as far as I go.
When you resubmit it, I'll check it in.
-- Jeff J.
Cheers, Shaun
