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.
