I don't see a problem either, I'm just suggesting an improvement on run-hooks. The improvement would reduce the number of times you have to define a wrapper around a function just to use it in a hook, by just not passing to the function more arguments than it accepts. Although, to be honest, I don't know how often that would be useful. Even in the case originally mentioned above it would actually *not* useful, because `save-buffer` *does* take an optional argument so the wrapper around it would still be necessary.

(add-hook '1-arity-functions 'some-zero-arity-function) (run-hooks '1-arity-functions some-arg) Here, it will throw an error because run-hooks will try to call (some-zero-arity-function some-arg). That's all fine and well documented, I'm just saying it may be more convenient if run-hooks took care to check that some-zero-arity-function has zero arity and invoked it without arguments.
