There is no vehicle needed.  As I said in the ticket, the only interoperable behavior
is to send a single SP. If some implementations choose to receive more than one space,
that's their choice -- it is still not interoperable to send more than one space.
The ABNF defines what is valid to send, not what is robust to parse.  I'd rather change
Apache httpd's parser to forbid extra spaces than make the request-line less predictable.
