(quoi qu'en pinaillant un peu, leurs bases s'entrecroisent...)
tu dois être en v 2.17 alors.
Ci-joint une version corrigée mais sans solution pour rapprocher les pointes de flèches.
On peut "masquer" cet espace en appliquant la valeur #t à \arrow-at-angle
mais je n'ai pas réussi à isoler dans le code ce qui me permettrait de n'avoir qu'une seule flèche, en
haut ou en bas...
et voilà :
