So why not add make targets for the chr files. Or I can do it in Jumbo, they would be handy right now while code is changing. They'd need a rockyou.txt that we don't supply though.

Also, I'm thinking we might want to do something like this:
* all.chr is actually made with filter_ascii, to be more like the old one.
* a new one, utf8.chr, is made with no filter (assuming pure junk was already removed/filtered, if we care about that).
* and a new ansi.chr is made from same data as utf8, but converted to CP1252.

With corresponding entries in john.conf, this will make some sense. --inc=utf8 and --inc:ansi are intuitive, and just -inc will be much like before (albeit with different training).

Btw I added filter_ascii and filter_alnum-case in bleeding yesterday. The latter is like alnum but using upper & lower case, and also includes space.
