[josm-dev] self-intersecting ways

[Matthias Julius]

The Join Node to Way command currently inserts the node into all way
segments within snap distance unless the node is already part of the
way segment or the way segments are consecutive.

This has the potential of producing self-intersecting ways by either
joining a node to a way it is already member of or when a node is
close to more than one non-consecutive way segments.  The validator
will put a warning on those ways.

I am wondering whether JOSM should actively support the creation of
self-intersecting ways or whether the Join Node to Way command should
only join a node to ways it is not already member of.

Also, I am wondering whether it should join a node only to the nearest
way instead of all ways withing snap distance.  If one wants to join
the node to another way one can just repeat the command.

Any opinions?
