Hmm. If we are not looking at "scratch", then does that mean skip_prefix() is the wrong function to use? I.e., should this just be:

  int local = starts_with(opts->destinations, opts->packdir);

It may still be worth pulling into a separate function to encapsulate the policy logic, but that function could be using starts_with() itself.
