[Message part 1 (text/plain, inline)]

`indent-region` is giving some weird results in c++-mode.  I will just
paste the main function here:

```C++
int main() {

  // looks good to me
  float nums[9] =
    {
      1., 2., 3.,
      4., 5., 6.,
      7., 8., 9.,
    };

  // wtf
  float * numsp = new float[9]
  {
    1., 2., 3.,
      4., 5., 6.,
      7., 8., 9.,
      };

}
```

In c-mode, the indentation looks fine:
```C
int main() {

  // looks good to me
  float nums[9] =
    {
      1., 2., 3.,
      4., 5., 6.,
      7., 8., 9.,
    };

  // looks fine in C-mode
  float * numsp = new float[9]
    {
      1., 2., 3.,
      4., 5., 6.,
      7., 8., 9.,
    };

}

```
