When processing multi-path ip6 routers, place each router entry on its

own line.  We made this change in traceroute(8) some time ago.  This
is particularly useful when you are not resolving hostnames since ip6
addresses can be quite long, and lines wrap fairly easily in the
multi-path router case.
