description:
Assume the HTTP/1.0 version by default.

It is believed to be better than fallback to HTTP/0.9, because most of
the clients at present time support HTTP/1.0. It allows nginx to return
error response code for them in cases when it fail to parse request line,
and therefore fail to detect client protocol version.

Even if the client does not support HTTP/1.0, this assumption should not
cause any harm, since from the HTTP/0.9 point of view it still a valid
response.
