[mkgmap-dev] r2829 in the high-prec-coord branch

Just a thought... could this also explain why I sometimes get told to
"keep left" at an exit on a straight motorway, which is a redundant way
of saying "do not take the exit"? I haven't been able to discover any
logic related to the tagging or the geometry in the OSM data.
