I can do that. Most of the changes make this overriding possible, where 
the permission is actually defined is a detail.

My reasoning is that finding the definition would not be 
straightforward. All the object-specific permissions so far are defined 
in "their" plugins, as determined by --type. This one won't have --type, 
and it's not clear if it should be in sudorule, sudocmd or sudocmdgroup.

But, I don't have a strong preference. A `git grep` will always show the
