Questions:

(1) Can anyone else reproduce this behaviour, or is it just some quirk

(2) Any possible explanations?  Is there some optimization that kicks
    in at a certain number of lines, or at a certain length of
    bytecode?
(3) If (2), is there some way to force the optimization, so that I can
    get the speed increase without having to add the extra lines?

I see no difference in execution times, as expected. The most likely explanation is simply that other things were going on on your system when you ran the first test, but not the second test, resulting in the discrepancy. In other words, the speed change had nothing to do with your dummy lines.
