Technically, the grant to public is a different target from the target
of the revoke in such a case. Following the spec would mean that even
when the grant and the revoke target is the same (unless you're the
original grantor) the right won't be removed. I'm not against adding a
warning in the case you describe though, but I don't see it being as
necessary for that case. What the spec describes is, at least in my
view, much more counter-intuitive than how PG currently works.
Thanks,
Stephen
