For routing to work across the tiles, the road end point has to be in
exactly the same place (well within 3 garmin units, about 20m) on both
tiles and they have to be marked as edge nodes.

mkgmap does this only if each tile has roads (etc) that extend beyond the
declared bounds for the tile and that those bounds match up exactly.
It cuts the roads exactly to the boundary and therefore knows that the node
it inserted is an edge node.
