I'd have thought a copy would occur and then the delete but if that
isn't the case then I can understand why the client doesn't make this
optimisation now as it would need to either move all such files to a
holding pen in case a copy is needed or it would need to look forward
in the transaction.

I don't know how far away atomic moves are but they will open up a
whole bunch more performance opportunities when they are done. I
originally thought they were being treated as compulsory for the
merge-tracking to be completed but I think I saw mention that this is
not the case... I hope the the nice people doing the work have time to
do it soon because merge-tracking and atomic moves are serious steps
forward for Subversion.

Is there a way of getting a '1.5 road-map' report from issue-tracking?
 I'm aware 1.5 is a ways off given that 1.4 has just been released but
it'd be nice to know what's on the horizon (even if those features
might change as development progresses).
