    _______________________________________________________

Details:

Following commands should remove variable from environment block:
    unset [name]
    save_env [name]
, like
    grub-editenv - unset [name]
does.

This is to prevent environment block from overflow by no-more needed variables
and to again fulfil requests like:
    if [ ! "${name}" ]; then ... fi
