[Talk-us] Do we want overlaps to be rendered? Or do we want to wait for relation support that may never come?

So I barely managed to get Mapnik working and played around a bit with 
shields. I didn't realize that each size shield was a separate image 
file. I guess that makes it a little harder - you need to filter by 
maximum line length after breaking at semicolons. I figured Mapnik just 
took the text, put a fill behind it, and rounded off the corners. If 
that were so, it would be a lot simpler to use wrap_character=";" like 
the motorway_junction code does.
