[mkgmap-dev] [PATCH v3] - Sub-optimal fix to limit excessive inter-node arc length

Hi, As most maps probably don't need this fix, here's a version of the patch that doesn't do the arc length limiting unless you specify the "--limit-arc-length" option. I have made the diagnostic message that is output when an arc length is too long into an error (was a warning) and it spells out what to do to get around the problem. Unless anyone has any issues with this, I intend to commit it (or something very similar) later this week. Cheers, Mark
