Actually the fact that the case of the filenames on Windows often changes by accident is what makes knowing that this happened so important. Some of the tools I use do care about the case of filenames, but now I can't find out about the changed filenames and revert them back easily. I agree that this probably is not very typical, but it would be good to at least have an option to see the case renames in 'stat'.
