Please be ware of the following:

  # rc.conf snippet
  static_routes="goodyear \
                 firestone \
                 bridgestone"
  route_goodyear="... "
  route_firestone="... "
  route_bridgestone="... "

  bridge_foo="... "
  bridge_bar="... "

Now `list_prefix bridge` will also list bridgestone because multi-line 
variables will not be properly detected by list_prefix.
