Subject: [PATCH] Make the menu entry users option argument to be optional
The --users option is used to restrict the access to specific menu entries
only to a set of users. But the option requires an argument to either be a
constant or a variable that has been set. So for example the following:
menuentry "May be run by superusers or users in $users" --users $users {
linux /vmlinuz
}
Would fail if $users is not defined and grub would discard the menu entry.
Instead, allow the --users option to have an optional argument and ignore
the option if the argument was not set.
