[OSM-talk] How to rollback the edits a new user made by mistake

[Niccolo Rigacci]

Hello,

yesterday I noticed some bad edits in a zone I'm mapping. I 
contacted the author (Israfil) and he promptly answered saying 
that it was a mistake, not knowing that it was editing the real 
map.

Some are new lines:
http://www.openstreetmap.org/?lat=43.5049&lon=11.2177&zoom=14&layers=0BFT

Other are moved points:
http://www.openstreetmap.org/?lat=43.53109&lon=11.14862&zoom=15&layers=0BFT

Because I (nor him) can say for sure where are the bad edits, is 
it possible to revert all the edits made by the Israfil user till 
yesterday?
