Details:

One should be able to put all arguments passed to a function into a single
(string) variable with all_arguments="$@". With grub-script currently, only
the first argument will be stored in $all. I assume that this happens because
of the way constructs like for arg in "$@" are supported, but it does not
match bash semantics. Example script which gives different results in bash and
grub-script:

function get_all_arguments {
  all_arguments="$@"
  echo "$all_arguments"
  echo "$@"
}

get_all_arguments "argument one" "argument two"
