[mkgmap-dev] highway=unclassified & area=yes

Hi all

Diagnosing what seemed like superfluous navigation pop-up, eg "Turn
left on A1", while driving on the A1, I discover quite a few junctions
are surrounded by a closed way with tags [highway=unclassified,
area=yes]

https://www.openstreetmap.org/way/239371846
https://www.openstreetmap.org/way/239371836
https://www.openstreetmap.org/way/239754207

and these "way"s, with the default style (and all other styles I've
ever looked at) will generated a road that probably shares many routing
points with the real roads in the junction.

These seem to be used for documentation of changes and are possibly
being create automatically by some OSM editing tool.

I haven't found any references to this being something that is
acceptable or is wrong, so I don't know if these should be deleted from
OSM and/or ignored by the mkgmap style.

Thoughts anyone -
