Ok then. I looked at some cGPSmapper-created maps that had dead ends  
without nodes, so I thought this was something legal, but probably  
those maps were just broken. I didn't ever try those out.

We could simplify the code a little if we assume that all road ends  
have nodes (see the startsWithNode-stuff in RoadDef).

I'd assumed that these problems were fixed by your earlier patch, the  
one with the incorrect offsets.
