AFAICT git does not store metadata about renames and just uses heuristic 
to detect moving/moving+editing/splitting of files, so something is 
possible at least in theory. 

But I would be happy is darcs could just "hint" on simple cases,  the 
user still has the chance to force the creation of a proper patch in the 
traditional way.. 

PS
I believe I accidentally deleted a message attached to this issue from 
the web interface, I'm very sorry.
