[sudo-users] per-user editor for visudo

I did consider that and, actually, with the following:

  Defaults:root   editor=/usr/bin/nano

visudo uses nano, overriding the --with-editor=/usr/bin/emacs option at
build time (however, aside, I have also noticed that with both the
Defaults:root entry above and a global:

  Defaults editor=/usr/bin/emacs:/usr/bin/nano

emacs is used; ie apparently the global Defaults wins)

However, and here I'm probably misunderstanding something, if I have:

  Defaults:balducci  editor=/usr/bin/nano, \
                     timestamp_timeout=-1,        \
                     !env_reset, \
                     !tty_tickets

then running "sudo visudo" picks all options (but for the editor) for
balducci; which makes sense to me: I run visudo as root, but sudo knows
who I actually am and loads my default options.

So: why is "sudo visudo" honoring all options for balducci, but for the
editor? what am I missing?

many thanks to all for the quick reply
