You're referring to incremental mode only. With the current publicly
released JtR code, you can only go to length 13 with incremental mode if
you restrict the character set to _one_ of the categories you listed
above. So what you describe above won't work.
However, it works great with the cutting-edge version we're using in the
contest now, with the default compile-time limit at 15 and the full
ASCII set allowed (you do have to recompile for the accents, though).
So why don't you join our team? ;-)
