In general, we attempt to avoid gratuitous changes in output like this.
We are out of options as well.. It was my intention that things like this
would come with a name change to pktdump.  pktdump would use all the same
code, but have a different main(), which different (saner) options, and
different defaults.

So, a patch to change this, optionally by flag in ndo->ndo_NEWFLAG would be
welcome, but I don't think we are going to change the default.
