SC2120 (warning): function references arguments, but none are ever passed.
In grub-completion.bash.in line 63:
__grub_get_options_from_help () {
^-- SC2120 (warning)
local prog
if [ $# -ge 1 ]; then
prog="$1"
The arg of __grub_get_options_from_help() is optional. So, the current
code meets the exception and does not need to be modified. Ignoring the
warning then.
