[OSM-talk] JOSM query

Right. Just came across a case that was a null-segment. Highlighting the node with box around showed the node and the segment in the current selection window. Careful checking to find the duff segment allowed it to be highlighted and then deleted. 
Ta for help.

	Normally this indicates that there is a zero-length segment at that
	node. The two common cases are:
	- Segment with from and to nodes the same
	- Two or more nodes at the same position with a segment between them.
	
	I fix these by using the "select area" tool, just draw a box around the
	node then look at selected items list. Normally you'll see multiple
	nodes and a segment listed for this single point in the map.
	
	Normally I select the segment and delete it. Then figure out which nodes
	aren't used by any other segments (e.g. one in the way) and delete them
	too (assuming they have no other attributes).
