Order of nodes in relations after unglueing

[rayquaza]

Yet another way to break a bus route: ;-)

• Create two ways (A and B) with a common endnode (N)
• Create a relation with the following objects: N, A, B
• Unglue the two ways

Usually one would now delete one of the doubled nodes (so it's no longer doubled). But have a look at the relation: It contains N1, A, B, N2. So you've got a 50% chance to delete the wrong node. A (hopefully) better result would be N1, N2, A, B.

In general it is a good idea to include the new clone members just below their origin.
