Just out of curiosity, I wonder why my following configuration as
discussed here [1], also can't solve the real-time display of search
results appeared in extremely long lines:

```
(use-package so-long
  :config
  (setq-default so-long-action 'longlines-mode)
  (setq-default longlines-show-hard-newlines t)
  (global-so-long-mode +1)
  )
```
