/  symbol will  block input text

Emacs 30+, my emacs is 31.0.91,  open any *.rs file, M-x visual-wrap-prefix-mode, type /, it will block any input text.

```
 (with-eval-after-load 'rust-mode
    (define-advice rust-in-comment-paragraph (:around (orig body) fix-eob-hang)
      "fix the / symbol crash"
      (if (save-excursion (end-of-line) (eobp))
          (funcall body)
        (funcall orig body))))
```
