upd: I tested this and tests run well.
I'm currently struggling to understand how to bruteforce my possible passphrases. Simply adding them to tokenlist and changing --mnemonic-length to 13 didn't work.
Oh, that's only a simple edit which isn't intended for bruteforcing purposes.
It's mainly for automating the search for your target derivation paths so you don't have to restore to Electrum one at a time.
But you still have to include all your candidate derivation paths in "
electrum.txt" file.
