    get_maintainers.pl: Avoid THE_REST when files are added or removed
    
    When files are added or removed /dev/null is used as a place
    holder name in the patch for the absent file.  Don't try and
    find a MAINTAINER for this place holder, it only ever flags
    and then spams THE REST, behaviour for a real filename is
    unchanged.
