How to detect copies?

[Frank Kingswood]

Hallo!

In perfarce.py I'm calling
	copies.copies(repo, ctx1, ctx2, repo[node.nullid])
to determine what files are copies of other files.

In some cases, the copies are not straight copies, but have modifications on 
top of the copy. In hg git-style diffs this is shown as a rename from, rename 
to followed by deltas.

P4 does not cope with this kind of modification so I have to turn this into 
another kind of operation.

The copies function does not appear to return this information. How can I 
detect this condition?
