Reword manpage to be more general (you do not only eject CD-ROM-drives, but BluRay-drives, floppy drives, LaserDisk-readers, toaster, whatever). Allow to specify multiple devices in the command line. Doesn't add LOC (the few more lines added are due to stricter error-checking) and might become handy for somebody in the future while not breaking scripts that assume only one argument. Crying like GNU coreutils when more than one device is given is not suckless: $ eject /dev/sr0 /dev/sr1 eject: too many arguments
