If you fail to update refs to change branches in checkout, your index and working tree are left already updated. We don't have an easy way to undo this, but at least we can check things that would make the creation of a new branch fail. These checks were in the shell version, and were lost in the C conversion. The messages are from the shell version, and should probably be made nicer.
