Empty nodes can also be left behind if you alter a way to update it
and in the process delete some nodes from the way, but then in JOSM
instead of doing upload data you choose upload selection with the way
that you changed selected. Then those node deletion actions don't get
sent to the server and your left with these empty nodes.
