Unconditionaly stripping \r is a bad idea because sometimes cat in grub
is used to determine why the system fails to boot. And if by a stupid
action fstab becomes DOS-formated 'cat /etc/fstab' will fail to show
this important point. But it's ok to add an option for cat'ing DOS
files. In this case we probably need to mark unix newlines somehow to
detect a reverse problem
