I have not found out how to do this in JOSM. However Potlatch exposes
deleted ways:
So I use that to undelete the way and then continue editing (or switch
back to JOSM)

I'm glad you raised this. This area really baffled me when I noticed
it a little while ago. I really didn't know how to resolve all the
duplication or how to approach the user in question - they have
obviously contributed a fair bit to the map but all the myid tags and
duplicated ways are odd.

As an example for the list:
The Muirs Highway has been duplicated (and upgraded to trunk which
also doesn't seem right to me).
