Oh yes! I knew that (it is clearly stated in man sudoers) but I didn't
recall it!

OK: I think I've got the point now.

Options like timestamp_timeout env_reset tty_tickets etc are expected to
be consumed by sudo; OTOH the editor option matters for visudo and not
for sudo (and, as you say, visudo runs as root when invoked as "sudo
visudo").

I'll build the latest commit and report
