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

Hi all

Checking the GBR, I detect 1865 of these highway areas. They are done
in a consistent and systematic way by a number of mappers.

I don't think it is a mapping error or an attempt to define the extent
of a junction as per the proposed tagging highway=junction.
Rather it is some option on the editing tool or some guidelines they
are following that says to do this as a way of documenting the changes
they have made within the junction area.

I'll ask some of the mappers why they are doing it.

These constructs can cause invalid routes to be calculated as well as
confusing/irrelevant direction pop-ups and I now ignore them in my
style.
