As a small example - I have a small Hamlet here called Bosfeld beloning to a
town called Rheda-Wiedenbrück with a suburb of Rheda.

The main street through Bosfeld is called "Bosfelder Weg" although all 
adresses are "Bosfeld 1" through 60 or something.

So mkgmap:street!=* will be wrong in finding the next routable way.
