If a setting like this is introduced, I would prefer that it be used to force Mercurial to use previous behavior. Otherwise, I've got to update everyone's global mercurial.ini and if I miss someone or they remove that setting, there is still a possibility of corruption.

I'd support a `moveonupdate` setting that causes Mercurial to use current "move on update" behavior.
