I think I added the necessary plumbing in r1132919, r1132924 and r1132948.

It already uses wc-ng (but can certainly be optimized further)
The problem with your version of the code was that it changed the value of
the metadata_only argument from TRUE to FALSE.
So instead of just changing wc_db and performing a single
svn_io_file_rename() on the move target all the actual files were copied.
(And then the originals deleted)
So instead of doing a single io-operation, we were reading and writing all
the on-disk data.

I think I fixed that part in those patches. That just leaves the question:
Which file should we leave after the copy?
I'm +0.5 on leaving the WORKING file, instead of replacing it with MINE.
This should match the 'svn copy behavior', maybe follow how we did it in
<=1.6 and above all make sense.
So I leave it to you to make a sensible decision here ;-)
