Std-1284 says it does: "The first two bytes are the length of the
sequence, including the two length bytes." Not only that, but "[t]he host
is required to interpret the first two bytes of the peripheral-to-host
message as a message length field" so we're not even supposed to ignore it
if it's wrong.
