Slightly faster method so that we don't iterate after we know the position of
the pivot:

    deleteOld() {
        local newFile oldFile found
        local oldFiles=()
        local newFiles=()

        while (( $# )); do
            if [[ "$1" == "" ]]; then
                newFiles=( "${@:2}" )
                break
            fi
            oldFiles+=( "$1" )
            shift
        done

        for oldFile in "address@hidden"; do
            found=0
            for newFile in "address@hidden"; do
                if [[ "$oldFile" == "$newFile" ]]; then
                    found=1
                    break
                fi
            done
            (( found )) || rm "$oldFile"
        done
    }


Also $arg, $newFile, $oldFile and $found should have been local in my first
posting.
