v3 : cinquième relecture — rien de ce qui touche un chiffre n'est une coquille

- Signature : tout caractère qui n'est pas une lettre latine et touche un
  chiffre compte, espaces et ponctuation comprises (« 5, 0 », « 1:5 »,
  « 1…5 ») ; un tiret compte devant ou après un chiffre à travers les espaces
  (« - 5 ») ; seules quatre espaces sont libres (ordinaire, insécable, fine
  insécable, saut de ligne).
- Négations complétées (guère, point, nothing, nobody, nadie, jamás…).
- Adoption : le texte qui entre en vigueur est celui qui a été compté — une
  révision arrivée pendant le passage l'arrête.
- Déploiement : « previous » est gardé avant le témoin de déploiement.
