That is what I had expected - I was only using it because the 'obvious
way' did not do what I wanted...

Does a GPS trackpoint count as a 'node' for this purpose?

That is exactly the process that I tried initially, but it results in
new nodes at each end of each segment. Even if I clamp the mouse in
position while clicking I seem to get two nodes in the same place.
This is easy to test - just make some 'joined up' segments and use the
move-node tool to shift one of the joins: one line goes with the node,
the other stays put.

Given the red circle that appears when you click, I had expected a
'snap to nearest existing node inside circle' behaviour.
