Finally, I believe we must support Tramp methods 'sudo', 'sudoedit' and
'doas'. I've prepared a patch (appended), could you pls check? The main
idea is, that for these methods the password of the previous hop is
reused. In case there is no "previous" hop, Tramp assumes a virtual one,
in order not to mix with the root password.

The patch is not polished yet, but I'd like to know whether it works in
general outside my laptop.

Thanks, and best regards, Michael.
