<pre>
    clang-format just gave me
```cpp
[[maybe_unused]] warn : if(count) std::fprintf(stderr, "%s: %s: truncated, %" PRIdoff "B lost\n", argv[0], file, count);
```
but if I comment the attribute out I get
```cpp
/*[[maybe_unused]]*/ warn:
        if(count)
                std::fprintf(stderr, "%s: %s: truncated, %" PRIdoff "B lost\n", argv[0], file, count);
```
which is as-expected.

Clang, of course, understands the attribute on the label as-expected here.
