Isn't <CR><LF> pretty much the standard in the RFC's ? IIRC RFC733 onward
all specify <CR><LF>. Since RFC733 and for the most part RFC822 pre-date
the PC revolution I would imagine that this was the standard convention
for the machines being used by ARPANET at the time (I was still using an
IBM1130 then and I don't remember what it used).

Perhaps a Net historian could step in and clarify the matter.
