jilles 6530d94c4a rc.d/routing: Fix ugly output with additional routing options.
Print a separate "Additional routing options" line for each address family
which has additional options, so that it does not get mixed up with the
output from adding routes.

This also reverts r224048 which added newlines to two arbitrary routing
options.
