Dear All (especially Eitan),

The allow_unknown parameter in navfn should allow to plan a path through
an unknown area. It does not seem to work. If there is an incomplete map
I would expect to get a path from navfn if the goal is in an unknown
area and the clear_goal_position flag is true.

Regards
Christian
