[mkgmap-dev] Duplicate roads added by default style

Mon May 10 10:16:34 BST 2021

It makes the style very complicated to try to remove any identical copies -
I do this by setting loads of temporary keys, that are checked later for
existing or not existing and based on that add or not add other lines.  I
guess some actual duplicates will still happen.
