As reported by Victoriia Egorova in bug 65880, grub-mkrescue does not verify that the expected argument of an option like -d or -k does really exist in argv. So, check the loop counter before incrementing it inside the loop which copies argv to argp_argv. Issue an error message similar to what older versions of grub-mkrescue did with a missing argument, e.g. 2.02.
