Seems it's not fixed yet:
```
$ cat test.cpp
{
    PyObjectPtr<PyObject> const readinto_method_obj{
            PyObject_GetAttrString(input_stream, "readinto")};
}
$ clang-format test.cpp
{
    PyObjectPtr<PyObject> const readinto_method_obj{PyObject_GetAttrString(input_stream, "readinto")
    };
}
```
You can correct the commit message and fix the issue in another patch.
