city wall inconsistencies

[nebulon42]

Line thickness varies between barrier=city_wall and historic=citywalls with the latter being on its own layer.

Example: http://www.openstreetmap.org/#map=19/49.61542/6.13741

The connecting line between the thicker line parts is tagged as barrier=city_wall while the other parts also have a historic=citywalls tag.

I am not sure is it a good idea to display historic=citywalls. Maybe it is expecting too much, but city walls may be mapped as building=*.

Current historic=citywalls rendering is not intuitive, especially in places with building=* - see http://www.openstreetmap.org/#map=19/41.90367/12.45770
