[mkgmap-dev] [PATCH v1] - fix splitting of ways when they have loops within loops

As predicted, the loop splitting code was under-performing. The attached patch should make it split all of the loops when a way has multiple loops. Before, a loop inside another loop was not being split (but a sequence of loops would have been). Those people who are seeing the new error message about consecutive nodes/bad routing should try this patch and see if those messages go away. Also, check if it breaks anything else. Obviously, it would be good to commit this soon if it works as expected. Thanks, Mark
