clang-format regression around return statements with explicit operator calls

[kadircet]

actual formatting:

struct S {
  explicit operator int*();
};

auto foo() {
  S s;
  return s.operator int * ();
}

expected formatting:

struct S {
  explicit operator int*();
};

auto foo() {
  S s;
  return s.operator int *();
}

That commit exposed a bug in annotating the star.

Starting with #136073, we now get the formatting of:

auto foo() {
  return sssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss.
  operator int*();
}

emphasis on the missing indentation before operator.

Re-openning this issues as they seem related, but I can file a new one if you prefer.
