Yes but the initial idea is good and the fix is straightforward so why 
not keeping it and send a patch of one line (or two if we want to keep 
the last if check) initializing the win variable to null. In that case, 
the function behaves as before the troublesome patch and the reading is 
simplified by some small rewriting. So all in all the original code is 
actually very good and fixing the mistake is simple. This is not 
important anyway it was just a kind suggestion.
