Oh, I don't know how I missed that.
(And I'll have to figure out what went wrong. But that shouldn't be too
hard.)

I thought about adding a more appropriate error message in this case.
But then I tested

$ ./john --incremental=doesnt_exist --stdout
No charset defined for mode: doesnt_exist

And then I thought, the first iteration doesn't need to be better than
the official john ;)
