if you remove the outer brackets of host spec, then that means that only the port may be repeated. The repeat is always meant to refer to its immediate preceding argument. The outer brackets make sure that it refers to either of both host *and* port. This is exactly what I was initially confused about. So I consider the outer brackets essential for that. Cheers, Paul
