I have a custom patch that uses istarts_with(), but it's not something
that will ever go upstream. I'll probably just switch it to do:

  skip_iprefix(..., &dummy);

which is equivalent. Not really an objection, but just mentioning that
unused functions may have ripple effects for topics in flight.
