Undo behaviour different when creating a way using existing nodes

[ggeldenhuis]

If I create a new way and press backspace it will take the edit back to the previously created node but I am still editing the way, a new click will create a new node in the way.

If I create the nodes first and the connect them using a way, pressing backspace will make the last "inclusion" of the node into the new way go away but will take me out of the way editing mode. I have thus to reattach to the way to continue editing it. The difference is subtle but noteworthy enough for me to raise a ticket.
