[OSM-dev] I've done some work on JOSM...

Does it fix the lollipop problem? This is when the final segment of a way
ends on one of the intermediate nodes in the way. These should be orderable
(if that is a word), because you can start either from the node that has
only segment from it, or from the node that has 3 segments as long as you do
the loop first.




I'm not sure what process there is for reviewing patches (if any), or

Posting it on this list should be sufficient. It used to be that Imi needed
to apply it to JOSM, but there is now another JOSM maintainer on this list
(deelkar?).
