Just dealing with nnml for a moment, what would it really take?  The
nov file already contains the message-ids of those in the group.

Just guessing here, but could some kind of hook into `B c' `B m' call a
function that would scan the message-ids of the incoming messages, and
compare them to the existing nov info in target `nnml' group?

If that were done would it slow things down terribly?

Lets say a match occurs, immediately gnus spits out a message. 
`Some messages already present in TARGET group.. continue?
User hits `y' and gnus makes the move.  
User hits `n' and gnus only moves those messages whos ids *do not*
match the nov info.  Any matching message are left out.

This would be quite an enhancement for those of us who copy and move
stuff around extensively... and are senile and forgetful.
