Well, didn't I do exactly the above much earlier and discarded it
because that breaks the definition of "diff"? Or is this doing
something differently?
Yes, and I try to sneak it in anyway ;-)
I spend some time debugging how to get t6038 passed, and need
some more time.
If 10/10 is a no-go (and it probably should be),
does it make sense to keep 1/10..4/10 and discard 5..10 for the moment ?
