I re-tested a sample I posted before with routing problems, except this 
time I converted the data to OSM format first, and it has the same 
problem with routing as I noted in a larger map, and as I explained above.

In the attached sample, snip.osm, if is not possible to route from

N13.10744 E100.92402

To
N13.09385 E100.91529

Without jumping all over the place (or any points points on these roads).

mkgmap inserts an extra node at

N12.978630 E100.917023
