For some reason, I have only received Christophe's mail, not Jakub's...

In any case, thanks for pointing out the existence of these functions.  I
just redid what Kees did in 2018, when I guess these functions didn't
exist.  I will look more carefully to see what functions are now available
and resend the whole thing.

Thanks!
