clang-format misindents field initializers inside range-based for initializer

[ilya-biryukov]

Run clang-format on this code:

void test() {
    for (const TestCase& test_case : {
           TestCase{
               .a = 1,
               .b = "1",
           },
           TestCase{
               .a = 2,
               .b = "2",
           },
       })  {}
}

In the output, the field names for the second fields are misindented:

void test() {
  for (const TestCase& test_case : {
           TestCase{
               .a = 1,
     .b = "1",
           },
           TestCase{
               .a = 2,
      .b = "2",
           },
       }) {
  }
}

I expect them to be at the same level of indent as the first field.
