It also seems to me it should work the way tcsh does as shown above.
I have noticed that the directory stack did not behave as I would
expect for quite a while and rarely use it with numbered arguments
because of that.  I just have not bothered to take the time to look
closely at what it was doing before now.  Dave pinpointed the problem.
Looks like it moves the entire rest of stack to the top rather than
the single entry like it does when used with no arguments.  It does it
on zsh-4.1.1 also.
