I'm not so sure about jumbo-8, but it appears that you've decided for
me, and I have no grounds to object - it is my fault that I haven't
released a new core version yet.  I am sorry about that.  I do intend to
resume core John development.

OK, although I think the revision to self-test should eventually be made
for all formats, and done() should be implemented for the GPU formats so
that they can be included in --test.  Aren't you merging the patch that
adds done() now?  Anyhow, you're the one to decide on this, as someone
more active at JtR development than I am. ;-)
