In the case of Mapnik, labels are repeated along lines by default, but its up to the stylesheet author to specify the spacing between them. So, it is the rendering rules in question really, not the renderer. > Cutting up ways just to make it look better for a certain renderer (Mapnik) > isn't really a good practice.
