For me the patch works very well (I don't know of any reason why I would 
need to have this behaviour tuneable via style-file, but as often, needs 
only arise once it is possible). Especially the annoying border 
artefacts of borders on the geofabrik cuttings are gone....
....
However even though I don't really know if it is the same reason. When 
compiling contourlines, there are also very often straight artefact 
lines crossing the whole image, maybe the same patch should be used when 
outputting lines 0x20-0x26 and 0x17??? (these are the contourline 
regions, and cannot be used for other features)
