Very nice.

We should see if we can incorporate this into the test suite, and if we
generate this data for other formats not yet in the ts, then do the proper
generation, and after the fact, get them into the ts.

NOTE, the TS as designed, would not be able to test the xxx2john
preprocessing type programs for bugs.  It's good you found this bug, but
this has not been designed into the TS.
