Potential new option: --delete-during

[Alberto Accomazzi]

Wayne,

I haven't (yet) given this a try but it sounds like a very reasonable 
thing to do.  --delete-before is still useful in those cases where you 
may be tight on diskspace.  But the default behaviour should be the most 
efficient one, so I agree with making this patch be the default --delete.

On a related note, don't you think it's time to start making candidate 
releases for 2.6.4?  It's been a while...
