C'est subtil... Il y a effectivement un -print implicite à la fin, qui fait que la commande habituelle sans print fonctionne bien, mais dès que l'on introduit d'autres commandes dans le lot (le --prune de FIND_VCS_CLAUSE), ça se corse à cause d'histoires de +-prune de FIND_SKIP_DIRS), ça se corse à cause d'histoires de parenthèses du -print implicite par rapport au parenthésage dans la forme recommandée d'utilisation: |
