conversion of tasks: add removing of -N

    # first regex replaces definition inside the ebmedded old QDEF format,

    # which is not really used, but should be kept in sync

    # the second one prelaces the proper definition in the new format

    # the third one removes unnecessary "-N" from task prefix

    sed -i -e 's/^:\(e[^=]*\)="f:/:\1="d:?/' \

           -e 's|\(<check><type>external</type><service>\)f\(</service><correct><!\[CDATA\[\)|\1d\2?|' \

        $i

    sed -i -E 's/([A-Z]{3}-[A-Z]{3})-N/\1/g' $i

done
