    get_maintainer: Add THE REST for sections with reviewers only
    
    Sometime, a contributer would like to be CCed on part of the changes,
    and it could happen that we end-up with a section that doesn't have
    any maintainer, but a Ack from a maintainer would still be needed.
    
    Rework get_maintainer so if there's no maintainers beside THE REST, it
    doesn't drop THE REST emails.
