(footnote string)

// there is already a footnote with the exact same text, reuse its
// number.
func (f *Footnotes) CreateCitation(footnote string) string {
	if footnote == "" {
		return ""
	}

	index, ok := f.indexes[footnote]
	if !ok {
		index = len(f.indexes) + 1
		f.footnotes = append(f.footnotes, footnote)
		f.indexes[footnote] = index
	}
	return fmt.Sprintf("[%d]", index)
}

// String returns a string representation of the footnote, including a
// trailing LF.
