About "volcano" in BIP39

"volcano" has 7 letters, but the first four, "volc", already identify it, because "vol" also begins volume.
"volc" is unique only within the English list: it also begins volcan in the French list and volcán in the Spanish list, so a four-letter backup should say which list it uses.
