Unusual function arg and closing function call parenthesis placement in dict hanging indent.

With Google style, yapf produces this:

```python
{
'a':
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(bbbbbbbbb
),
}
```

I'd expect the function argument to be on the next line with the parenthesis, like this:

```python
{
'a':
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
bbbbbbbbb),
}
```
