About "obscure" in BIP39

"obscure" has 7 letters, but the first four, "obsc", already identify it, because "obs" also begins observe.
"obsc" is unique only within the English list: it also begins obscur in the French list and obscuro in the Portuguese list, so a four-letter backup should say which list it uses.
