Good morning everybody,

For the record (from the man page):
| -h host, --host=host
| Run the command on the specified host if the security policy

That says that the -h host notation has two uses: To run a remote
command (which is not supported by the suoders plugin anyway) and to
list a user's privileges for the remote host.
I'd interpret this as reprotest's call sudo -h localhost using
undocumented behavior.
I will talk to sudo upstream about this and report back.
Greetings
Marc
