    Commit https://github.com/llvm/llvm-project/commit/5c2e7c9ca043d92bed75b08e653fb47c384edd13 introduced a regression (w.r.t. v13). @mydeveloperday

Style: LLVM

Input/expected:
```
template <typename = void> struct S {};
template <> struct S : Template<int (*)[]> {};
```

Output:
```
template <typename = void> struct S {};
template <> struct S : Template<int (*)[]>{};
```
The first line is for comparison only.
Mind the missing space before `{}` on the second line.
It seems that `[]` are now 

This code is just a minimal repro of https://github.com/tcbrindle/span/blob/master/include/tcb/span.hpp#L274 (a bit differently formatted):
```
template <typename, typename, typename = void>
struct is_container_element_type_compatible : std::false_type {};

template <typename T, typename E>
struct is_container_element_type_compatible<
    T, E,
    typename std::enable_if<
        !std::is_same<typename std::remove_cv<decltype(detail::data(
                          std::declval<T>()))>::type,
                      void>::value &&
        std::is_convertible<
            remove_pointer_t<decltype(detail::data(std::declval<T>()))> (*)[],
            E (*)[]>::value>::type> : std::true_type {};
```

Using config `BreakBeforeBraces: Allman` makes the issues be even more visible (but is not related AFAICT).
