I wondered if this would trigger for "http.*.extraheader", too. And it
should, as that is all handled in the caller of http_options. Good.

This looked wrong to me at first, because we are appending to the
default header list in each case. But the secret sauce is that calling
http_get_default_headers() actually creates a _new_ list that is a copy
of the default headers (and the caller can do what they will with it,
and must free it).
I think that's really the only sane way to do it because of curl's
interfaces. But maybe it is worth a comment either here, or along with
http_get_default_headers(), or both.
