I feel I'm partially to blame. Jovi has sent us several emails to look
at his tree and I told him I would when I get time. What I should have
done was told him to break up the changes and send them out as a patch

Again, this may be partially our fault. We should have told Jovi to send
out the patches and a pointer to a git tree is not acceptable. Then we
could have had the necessary discussions required for this.

But I agree, this should not be just dumped into the staging tree until
the patches themselves have been posted and reviewed.

I'll have to NAK it too.
