I get that exclusions are useful, my concern is that the command "breakpoint delete" doesn't delete what you give it. If `break delete foo` deletes foo, then on the surface `break delete --disabled foo` should also delete foo. The flag does what it says, but also silently inverts the meaning of the positional args.
