Oh, things are not so good: I totally forgot that --loopback does not
combine LM hash halves (indeed, it does not have/know the input password
file to do so).  So we're back to the approach with "cut", and this has
the colon problem.  A solution may be to enhance --show so that we could
tell it to output first two fields only (then we'll use "cut -f2-").
Another solution may be to get some LM2NT functionality into JtR proper.
