"--loopback" is not in core JtR, it is a fairly recent addition to jumbo -
in fact, I did not recall it when writing my previous reply.  I think it
addresses the issue with colons.  So I think things are pretty good as-is,
except that maybe we need to write a tutorial or something.

Anyhow, this is more of a john-users topic than a john-dev once.  I see
why this is on john-dev, though - because the discussion started with a
proposed patch.
