Ugh, I think you are right. It's been a long time of course, but it sure
looks like that was copied-and-pasted without recognizing that it was
wrong in this function because of the need to check the admin_option flag.
And then in the later security discussion we didn't realize that the
problematic behavior was a flat-out thinko, so we narrowed it as much as
we could instead of just taking it out.
Does anything interesting break if you do just take it out?
