What you're describing is not a simple rotation, since you're
restructuring the tree quite a bit more than that. In any case there
should certainly be no copy operations in the editor drive.

    $ svn st wc
    R + wc/A

Hm .... it would appear that EV2 rotate needs the concept of virtual
temporary nodes in order to represent something like the above.
