Sure. It's a completely separate matter, just with some interactions 
(will follow-up on that report as soon as I've enough time: did more 
researches but as you noticed the commit history is pretty long and not 
always so linear).

I agree. My point here is that I would avoid modifying the behaviour of 
'-r' (even if it's considered "wrong") while working on '--link', as imo

would do. Well... and also that dereference settings in cp should be 
reorder a bit (but again it doesn't belong here).

Ciao,
Gian Piero.
