Torsten,

it's the other way round. The patch tests for all unclosed ways that are 
assigned with a garmin polygon type if both endpoints are outside the 
bounding box. Only in this case the polygons are closed automatically.

Before r1865 all lines that were assigned with a garmin polygon type 
were closed automatically.
