OK, this makes sense (though again, at some point we want this to stop
being a "ref_format" and just be a "format").

Does this need to be a pointer? We can just store the ref_format inside
the struct, right? And then...

...here you would not need the extra local variable. You can initialize
it like:

  struct batch_options batch = { REF_FORMAT_INIT };
