About "grass" in BIP39

"grass" has 5 letters, but the first four, "gras", already identify it, because "gra" also begins grab, grace, grain, grant, grape and gravity.
"gras" is unique only within the English list: it also begins grasa in the Spanish list, so a four-letter backup should say which list it uses.
