Allow complex port list specificition for nc(1)

4. Technical Description
The current implementation of nc(1) only supports a single port or one
port range what makes working with multiple ports not belonging to a
certain range inconvenient. Therefore nc(1) should accept a list of single
ports and port ranges as a parameter to avoid multiple calls to nc(1) for
each port or port range.
