It was mixed-up if hostname is IPv6 address, and reporting separate values (like port) on separate lines fits better into key-value style of 'show protocols all' output. Also, the patch simplifies transport identification formatting (although it is unused now). Thanks to Alarig Le Lay for the suggestion.
