I saved all the original source data and the id mappings from the source
data to the OSM database.  

For each of the source ways and nodes, I can look up the OSM version and
download it.  Then, compare what I downloaded to what was originally
uploaded.  If they're the same, add a tag, or just make a trivial update
to the way/node to get it moved to another userid.
