   İki sorun vardı: (1) liste bloğu 66ch genişlikte ama sola
   sabitliydi, paragraflar ortalıyken liste sola kaçıyordu;
   (2) satır başındaki ">" işareti ortalanmış metinde her
   satırı farklı yerden başlatıp dağınık gösteriyordu.
   Blok ortalandı, işaret kaldırıldı — ayrımı kesikli çizgiler
   zaten yapıyor.                                             */
