We're deprecating vim modelines in favor of `.editorconfig`.
Removing vim modelines could be done using two one-liners. Most of the vim modelines
were followed by an empty line, so this one-liner took care of these ones:
```sh
rg '^# vim: .+\n\n' -l | xargs sed -i '/^# vim: /,+1d'
```
Then some of the vim modelines were followed by a pylint configuration line, so running
this one-liner afterwards took care of that:
```sh
rg '^# vim:' -l | xargs sed -i '/^# vim: /d'
```
This unfortunately gets quite a bit more cumbersome, as we can't easily
parametrize an annotation anymore - the former `typ` will just be lazily
evaluated as the string "typ".
Closes#5769
When we have something like "*values: str" in :config-cycle, we get a list of
values, but the type converter assumes it's a string.
We could implement proper conversion of *args, but for now, let's just make
sure it's always a string.
