It seems that if an xferfunction is used *and* CURLOPT_FOLLOWLOCATION is
enabled, the redirection is not taken after the 'Location:' header field
has been seen, but after the redirect*ing* document has been read. This
behavior is not in line with libcurl returning the redirected-*to*
document (instead of the redirect*ing* one or everything) on redirects.

The latter behavior is fine (see also
<https://curl.haxx.se/mail/lib-2014-08/0171.html>), but the former is
not.
