NAK.
We already print the cause of the abort earlier in the dump, and we've
also added a "cut here" marker to help people include all the necessary
information when reporting a problem.
It's unfortunate that we have the additional colon in the oops dump,
but repeating the information that we've printed on one of the previous
two lines is really not necessary.
