Yes, at some point.
If we did this at 'commit'-time instead, the merge info for the
destination of the 'copy'/'move' would not be correct. Any merges
would then need to do that same history tracing as part of the
'merge', smearing the implementation details across commands....ugh.

Good question. This is probably a (rather significant) change in
behavior for what I assume was previously a disconnected operation.
Anyone else have thoughts on this?
