[mkgmap-dev] [PATCH v2] Fix Nuvi routing regression (rebloat Table A)

Hi Marko,

Thanks for the report.

Not sure about that but I do think that this warrants some more work to
try and understand exactly what the constraint is. It's interesting
that it doesn't appear to have any effect on mapsource (or the etrex,
as far as I can tell). I don't favour making it configurable because
then the map makers would need to say what units their maps are
compatible with. Far simpler to take the hit on map size (and possibly
routing performance) until we know what's really happening.

Thanks, I reckon it will be OK for them now.

Cheers,
