Actually, I think this is a different topic, not closely related to this
thread's original Subject and requesting a different feature. In fact,
you did not quote any context because there was nothing relevant to
quote. So I would have preferred to see this in its own thread. I've
merely changed the Subject now (but did not break the thread).

We used variations of this Perl script (referenced from the john-users
team writeup):

Yes, I agree that JtR should gain builtin multi-word support for
wordlist rules. It already has this feature (for working with two words
at once) for "single crack" mode (in fact, it did since 1990s), but not
for wordlist mode yet.
