        <pre>The following code doesn't get formatted properly"

struct A {
  int idx_;

  // prefix increment: fine
  constexpr A& operator++() noexcept {  
    ++idx_;
    return (*this);
  }

  // postfix increment: no space between (int) and noexcept:
  constexpr A operator++(int)noexcept {
    A tmp(*this);
    ++(*this);
    return tmp;
  }
};

As you can see there is no space between the arguments of postfix increment and
the noexcept qualifier.

I haven't tried but the same might be true for other function qualifiers
(const, override, final), for function reference qualifiers (&, const&, &&),
and other operators like --, *, ->, /, ...</pre>
