The problem here is that we now require the update before moving. If we can
postpone that requirement to the commit time, there is no problem for
clients like Subclipse and AnkhSVN. A move or copy is an operation that is
performed as part of larger operations, while commits and updates are not.
Those operations are specific to version control.

Moves and copies are often contained in automated tasks like refactoring
tools.

And those refactor tools might change many files, move files, change more
file, move a few more files. And you can't just fail in that last step.

Requiring the user to then perform an update before committing is no
problem. But breaking powerful refactoring tools is.
