About "custom" in BIP39

"custom" has 6 letters, but the first four, "cust", already identify it, because "cus" also begins cushion.
"cust" is unique only within the English list: it also begins custode in the Italian list and custear in the Portuguese list, so a four-letter backup should say which list it uses.
