I'm not actually talking about deferring anything. I'm saying that we need
*never* to record mergeinfo for copy operations because the item's history
carries the information already. That we store it is merely an optimization
which prevents us from having to query the server about it later, as far as
I can tell. Granted, that optimization might be a very important one that
we'd prefer not to abandon -- I haven't thought that far through the matter.

Yes, and yes. :-)
