Sorry, I should've been more clear. I'd prefer that we allow the operation in
the WC rather than forbid it. I assumed that this ability was allowed for a
reason, but it may have just been an implementation detail of the RA layers
that allow this to occur there.
The command line client can most certainly do more complicated rearrangements.
I've had great success in rearranging entire source code trees, modifying the
build environment, and committing it all in one nice changeset.

It's in the contrib area. It's a tool written by Philip Martin which allows
you to do multiple repository side copies, moves and deletes in a single

My reasoning was consistency. If it doesn't make sense in the WC, how does it
make any more sense at the RA layer? But I guess that's not enough reason by

As I said before, I've been away from any real development for a while now.
You guys are certainly much closer to the issues. Please do as you see fit.
