Instead you could credit him with Helped-by:, perhaps in place of
Reviewed-by: somebody who does not have any commit in our history,
which does not help others decide how good this patch is because
they do not know how much trust they should place in the ability to
review of somebody they never have heard of---Simon may be a super
human programmer whose name alone should assure us that a patch
endorsed is good, but the thing is, that won't happen until we know
that.

The patch looks good.  Eric may say "This round looks good to me"
before I have a chance to queue it, in which case I'll add his
Reviewed-by: and queue.  In either case, unless there is something
else comes up, there is no need to resend this patch.

Thanks.
