I thought it made it harder by moving the terminating 1 bit out of the
driver proper, where it has a symbolic name.  Thus someone comparing
the driver to the spec has to read another source file to figure out
how the driver gets that bit set.

As it is, the straight-line code in the driver corresponds very simply
with the packet as illustrated in the data sheets.

I agree it's really really minor either way, but so is the saving
we're going for.

Since it's not *clearly* an improvement, I err on the side of not
messing with a driver I can't test.
