By the way, a few Italian cities have "name:en" tags, notably Venezia 
(Venice), Roma (Rome), Firenze (Florence), Milano (Milan) and Napoli 
(Naples) IIRC. It would be a shame to lose these, but there are 
sufficiently few they can be added back manually. It would be worse to 
end up with duplicate places.
