[ns] 'orient' does not work?

[Apu Kapadia <akapadia@uiuc.edu>]

The following code doesn't seem to work, i.e., nam doesn't show anything
in the window. I found the same results with the example scripts that use
the 'orient' option. Has anything changed?

$ns duplex-link-op $n(0) $n(1) orient right

Thanks,
Apu
