Hi @richtja,

This one took me a while (and it surely took you even more time), so thanks a lot! It looks good to me, and I tried to solve the conflicts at merge time, but the changes are quite big.

I guess it's better to rebase this and make it go through CI again.

Hi @clebergnu, I did a rebase to resolve conflicts with the master. Please take a look.
