```
C:\Users\bion\Desktop>type bug.cpp
template<class X>
inline constexpr bool is_nothrow_swappable = true;

template<class...>
struct X {};

template<class A, class B, class C, class D, class E>
void swap_all_the_things(X<A, B, C, D, E>&, X<A, B, C, D, E>&)
noexcept(is_nothrow_swappable<A> && is_nothrow_swappable<B> &&
is_nothrow_swappable<C> && is_nothrow_swappable<D> && is_nothrow_swappable<E>)
{
}

C:\Users\bion\Desktop>clang-format --version
clang-format version 8.0.1 (tags/RELEASE_801/final)

C:\Users\bion\Desktop>clang-format .\bug.cpp
template <class X> inline constexpr bool is_nothrow_swappable = true;

template <class...> struct X {};

template <class A, class B, class C, class D, class E>
void swap_all_the_things(X<A, B, C, D, E> &, X<A, B, C, D, E> &) noexcept(
    is_nothrow_swappable<A> &&is_nothrow_swappable<B> &&is_nothrow_swappable<C>
        &&is_nothrow_swappable<D> &&is_nothrow_swappable<E>) {}

```

Note that the &&s are attached to the following variable template instead of
having an extra space.
