I had not followed this thread, sorry. I didn't know the Geofabrik diffs 
had this problem, but of course if one thinks about it, it does seem 
logical - comparing two excerpts, when the newer one doesn't have an 
object then how am I to know who deleted it when and in what version?

I could run Jocelyn's patch on the Geofabrik server but technically it 
would create wrong osc files - if you were to compare a Geofabrik osc 
with one loaded from osm.org you'd find that the Geofabrik diff reports 
the wrong user name, wrong timestamp, and *possibly* also wrong version 
on a deleted object.

No idea if that problem is worse than the one we have now!

Bye
Frederik
