A new buffer to a new file path before first save with adjustment to
mode kind and comment start prefix convention triggers the suggestion to
M-x revert-buffer
for change to take effect, which turns out to be incorrect for a
buffer never before saved to file.
M-x normal-mode
does the job correctly.
Steps to recreate
1. run, emacs -Q -nw
2. load theme womat for readability, dark blue on black is unreadable on input buffer below mode line
3. open blank buffer to file without saving, /tmp/x
4. type at top of file, # This comment line is left intentionally blank. -*- prog -*-
5. add prop line, M-x add-file-local-variable-prop-line
6. enter, comment-start: , "# "
7. *Messages* buffer says, For this change to take effect revisit file using M-x revert-buffer
8. *Messages* says, revert-buffer-insert-file-contents--default-function: Cannot revert nonexistent file /tmp/x
9. M-x normal-mode ; does the job suggested at 7. above

No further comments, so I assume the problem is indeed solved, and I'm
closing this bug.

No, because it was too late, and the change is in a sensitive place.
The issue is also not new: this code was added to Emacs 10 years ago.
Sorry.
