Yeah, I noticed that this patch was sent bt GGG. But since he has
already added "Cc" at the end of the commit message, yet in the actual
email header, there is no "Matthew John Cheetham", which was confusing?
This is something I forgot to mention in the previous email, sorry.

I may have to take a closer look at GGG later.

Thanks!
