I have a migration script in the works that will convert unwayed segments and
tagged segments to 2-node-long ways, but it takes an order of magnitude longer
than the old one.  Damn, I'll have to rewrite it in C.

As for finding these ways, I think you could use the validator plugin for
that.  Furthermore, I have just extended JOSM's combine way action to combine
overlapping ways correctly.  You'll just have to select the converted segment
and the way it was previously part of and hit combine ways.

  Gabriel.
