When you uploaded those ways you should have gotten the new way_id. If
you didn't record this but remember on which day you did the upload you
can download the right daily or hourly diff (from
http://planet.openstreetmap.org/) and find the IDs in there. (And record
the IDs the next time you do a bulk upload for cases like this.)
Ok. I found the IDs of the ways I would like to delete. What do I do next
to retrieve them and remove them. Thanks.
