dup-to, as described, does not do what I wanted.

The doc says "optionally with the destination IP address changed to
that specified".  This sounds to me as though it rewrites ip_dst in the
packet (which seems to me to be the Wrong Thing, even for dup-to).

This is all reminding me of email, with its distinction between
envelope and header recipients.  Using that analogy, I wanted to
specify the envelope-to address, not the header-to, and that's what I
think it should do even for dup-to - but the doc reads as though it
changes the header-to, or at least it's not clear.
