As far as I remember that behavior is intentional, as indicated by
the succeeding test.
The whole MIN_BLOCK_LENGTH thing is a hack IMHO as we did not have
a better heuristic for suppressing uninteresting "moved" lines such as closing
braces in C.
The information that a thing is moved in between two blocks is more
valuable than pointing out it is just 'new' or 'old'.
As this is changing behavior in a way that seems controversial, can you
give your motivation/example for why this behavior is better?
(Do we want to put it into an option/mode?)
