I don't know if this is a bug or just a feature of emacs. Therefore, I'd
better ask here first.

1. emacs -Q <RET>
2. C-x C-f some-non-existing-file-name <RET>
3. M-x add-file-local-variable-prop-line <RET>
4. coding <RET>
5. iso-2022-jp <RET>
6. Told to revert file for effect to take place.
7. M-x revert-buffer <RET>
8. yes <RET>
9. Told cannot revert nonexistent file.

The same effect occurs with other codings, for example utf-16 - but not
with utf-8-unix. I'm using emacs-28.0.50.
