Guile manual for `format':
  
  address@hidden gives roman numerals and ~@:r gives old roman numerals. In old
  roman numerals there's no “subtraction”, so 9 is VIIII instead of IX. In
  both cases only positive numbers can be output.

               (format #t "address@hidden" 89)  -| LXXXIX     ;; roman
               (format #t "~@:r" 89) -| LXXXVIIII  ;; old roman

If "IV" is supposed to be the correct output, iso. "IIII", then the
"address@hidden" format directive should be used in scm/fret-diagrams.scm,
iso. "~@:r".
