fn hanging_labels<'labels, 'diagnostic>(
    single_labels: &'labels [(LabelStyle, Range<usize>, &'diagnostic str)],
    trailing_label: Option<(usize, &'labels (LabelStyle, Range<usize>, &'diagnostic str))>,
) -> impl 'labels + DoubleEndedIterator<Item = &'labels (LabelStyle, Range<usize>, &'diagnostic str)>

Return an iterator that yields the labels that require hanging messages rendered underneath them.
