[exim] Query regarding docs for 4.60

Hi,

I was reading the docs (I know, shocking) and came across this bit at
this link:
http://www.exim.org/exim-html-4.60/doc/html/spec.html/ch05.html#id2533742*

-oMr* </protocol name/>

    See *-oMa* above for general remarks about the *-oM* options. The
    *-oMr* option sets the received protocol value that is stored in
    /$received_protocol/. However, this applies only when *-bs* is not
    used. For interactive SMTP input (*-bs*), the protocol is always
    “local-” followed by one of the standard SMTP protocol names (see
    the description of /$received_protocol/ in section 11.9). For *-bS*
    (batch SMTP) however, the protocol can be set by <<*-oMr*.

I'm wondering if the "<<" is meant to be there and represent the fact
that it should be sent as part of the input stream to exim, or if it is
still a command line option and the "<<" have appeared magically?

Thanks,

Gary
