[p4] Python mMarshalling problem

[Robert Cowham]

On Windows you have to do popen with mode 'rb' as opposed to just 'r' being
required on unix.

A little gotcha for the unwary.....

      if os.name == 'nt' :
		mstream = os.popen('p4 -G labels', 'rb')
	else:
		mstream = os.popen('p4 -G labels', 'r')
