Without a typ file, the Edge 705 ought to show a black line (0x0d or 
0x0e) overlaid with the dashed brown line (0x07).

Yes, that would make sense when using a TYP file.

I got another idea: What if we create a default-typ style based on the 
default style, similar to the marine style? It would define overlays for 
bridges, tunnels, oneways and such. The prerequisite for this would be a 
TYP file that can be distributed with mkgmap (with an appropriate 
license and some maintainer). The default-typ style would only contain 
the tweaks; most definitions would still be in the default style.
