visudo uses the EDITOR / VISUAL vars, see the man page:
ENVIRONMENT
The following environment variables may be consulted depending on the
value of the editor and env_editor sudoers variables:
VISUAL Invoked by visudo as the editor to use
EDITOR Used by visudo if VISUAL is not set
See, these variables are used *by visudo*. As you said, sudo is needed
only for the user, otherwise I get 'visudo: /etc/sudoers: Permission
denied'.
