How is it valid?

Just this part.  Any patch output that correctly explains how the
preimage text changed to the postimage text is a "valid" diff, and
that is how René used the word.

To be clear, the "valid" in my question is about the correctness of
the expected behavior,...

I know that, and that is why I clarified that you two are using the
same word differently.

In any case, I think that I now see the problem: the (sparse)
explanation says "Ignore changes whose lines are all blank.".  It
would have been helpful to clarify with "(but blank likes that are
*part of* a change are still shown)".

Looks sensible ;-)
