Of course it works.  The part you quoted was the introduction
and was as it "should" be.  You cut out the part with the actual
question.  I'll repeat it here:

    So far, so good -- but look at this:

	$ rmdir bar/
	$ ls -l
	total 0
	lrwxrwx---  1 gjb  wheel  3 Feb  4 06:35 bar -> foo
	$ 

    Oops, "rmdir bar/" ended up as "rmdir foo" and left the useless
    symlink bar in place.

What I'm saying is that the ls above should have shown the
directory foo, because "rmdir bar/" should not result in doing
the same as "rmdir foo".  IMO, "rmdir bar/" should elicit the
same response as "rmdir bar" -- "Not a directory" and no action.
