Oh... yea... nice. 20% faster... Clearly the better choice.
Something to remember for small loops. So, Dan, what other tricks
do you have? :)

BTW, I copied the wrong timing numbers for the move instruction.
It should have been

                     head/tail/cycles
move.b(a1)+,(a0)+    1    2    8(1/1/1)
                                ^^^^^^^ that's better
