About "exact" in BIP39

"exact" has 5 letters, but the first four, "exac", already identify it, because "exa" also begins example.
The same spelling is in the French BIP39 wordlist, but as word #758 (index 757), not #627. A wallet set to French reads "exact" as 01011110101 instead of 01001110010, and decodes index 626 as "édifier".
"exac" is unique only within the English list: it also begins exacto in the Spanish list, so a four-letter backup should say which list it uses.
