Re the ways with no segments; Tom Hughes has been looking at this type of
data integrity error and some fixes are expected soon. A change is required
to JOSM as part of this process, once all these ducks are in a row it's
hoped that these data errors can be cleaned out. I believe this process
should clear up your latter query too, although some manual intervention is
likely to be required in some instances to deal with ways that have valid
but wrong segments.
