[mkgmap-dev] line features are converted to a closed way

From WanMil wmgcnfg at web.de on Mon Sep 20 19:44:31 BST 2010

The coastline log errors come from the special coastline handling which 
has nothing in common with the described problem.

Attached patch performs only the line styles on unclosed ways (the patch 
is untested!!).

Please consider the following:
1. Line rules must be performed on polygons (==closed ways). Otherwise 
all roundabouts and other circular streets will disappear.
2. Due to the tile splitter lots of polygons on the tile border might 
not be completely contained in the tile. I'm not sure if these ways are 
closed or not.
