The script uses sed to modify the options field in the BLS entries, but it
is using a ',' character as the sed delimiter. It's total valid to have a
kernel command line parameter that contains that character, for example:
$ grubby --add-kernel=/boot/vmlinuz --args="console=ttyS0,115200n81" \
--initrd=/boot/initrd.img --make-default --title=install
sed: -e expression #1, char 42: unknown option to `s'
Fix this by using a different delimiter that won't be present in a cmdline.
