yes, the original test was without w3. I wanted to prove that the 
link-pois-to-ways-v2.patch doesn't change something to the worse
as feared by Chris66 :

The test proved that, so I wanted to find out what MapSource does if there is an 
alternative connection which is much longer. Result is the test case.
Later, I've modified w3 to be much shorter, but that did not change 
anything to the better, means, all results with wrong routes were the same.
