<pre>
    Given the following code (https://godbolt.org/z/YrEnGb35W):
```cpp
bool b(nullptr);
```
clang emits the warning:
```
<source>:1:8: warning: implicit conversion of nullptr constant to 'bool' [-Wnull-conversion]
bool b(nullptr);
     ~ ^~~~~~~
       false
```

However, no conversion should take place here; instead, this is a special case:
> Otherwise, if the initialization is *direct-initialization*, the source type is `std​::​nullptr_t`, and the destination type is `bool`, the initial value of the object being initialized is `false`.

\- [[dcl.init.general] p16.8](https://eel.is/c++draft/dcl.init.general-16.8)

## Suggested Fix
The warning should instead state:
```
direct-initialization of bool to nullptr
```
