The manpage says:

I want to ignore files under `.mypy_cache`, `.ruff_cache`, and
`.pytest_cache`, and so I tried:

```
inotify-hookable -d -w . -i '\..+_cache' -C '.+\.py$=pytest -s'
```

and also every other combination of regexp I could think of, including
the use of `qr{}` and even just `.*`, but none of these seem to have any
effect, leading me to believe that `-i` is broken, or very wrongly
documented.

Thanks for looking into this!
