[OSM-newbies] Ungluing in Potlatch

[Mike Harris]

This was discussed a while back and I don't think there is a consensus.
There are cases where having a common way for the road and the landuse area
does cause problems e.g. in more detailed mapping (which often comes later
than the original creation of the common way with shared nodes) that wants
to show features that arise from the real-life finite (non-zero) width of
the road without implying that the land-use (e.g. farm) applies to the road.
At its worst, there are cases where the landuse occupies a single polygon
with roads running through it.

SO ... I would defer to the poser of the original question - if (s)he thinks
it is worth doing (and it is so much easier on JOSM isn't it!) then it is
probably worth doing ...
