For the peoples who like to use auto-save-visited-mode with 1s interval,
this minor annoyance will become major annoyance.

Hope someone expertise on ns port can fix this issue in Emacs 29 or 30.


My use case is auto-save files with every second of idle time:

```
(setq auto-save-default nil)
(setq create-lockfiles nil)
(setq make-backup-files nil)
(setq auto-save-visited-interval 1)
(auto-save-visited-mode 1)
```

Or, is there any workaround to suspress the message when saving file?
