The server is documented as MUST NOT send additional refs,
which is fine here, as we'd have no way of storing them anyway.
Do we want to issue a warning, though?

    if (!r) /* never break'd */
        warning ("server send unexpected line '%s'", reader.line);

Can we rename that to exact_oid ?
(bonus points for also converting expect_old_sha1)
