Minimal repro
Formatting this C++ program with clang-format (i.e., using the default style):
template <class> class S;
template <class T> bool operator<(S<T> const &x, S<T> const &y) {
return x.i < y.i;
}
template <class T> class S {
int i = 42;
friend bool operator< <>(S const &, S const &);
};
int main() { return S{} < S{}; }
Transforms the well-formed friend declaration into the ill-formed:
friend bool operator<<>(S const &, S const &);</pre>
