Ah, I missed that it is attempting to return the body, too.
Because the function takes an open filehandle, I think it is better
to leave it to the callers. A caller that is only interested in
headers can just close $fh after this helper returns without reading
body that it is not interested in, and a caller that wants to read
the body can do the slurping itself.
