Yes, port 0 is the way to leave a dissector unattached to a port.  This 
allows the user to specify a port in the preferences or to right click 
and choose decode as and pick the protocol in there.

I tested it on FreeBSD / x86.

Great work; thanks for your contribution!  I changed the indentation 
from 2 spaces to tabs [intended to be 8 spaces wide] as that is the 
preferred method for new code.  Did you use Emacs to write the program?  
That and other programs let you change the default indentation logic.
