Unaligned lambdas in while loop body

yapf (tested with 2c13f6f93e8ccfa0c966b67f88eeffe20ccb32a0) turns the following:

```python
while A(
b"\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00",
(lambda: b"\x00\x00\x00"),
):
pass
```

Into the following:

```python
while A(
b"\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00",
(lambda: b"\x00\x00\x00"),
):
pass
```

pycodestyle calls this "E131 continuation line unaligned for hanging indent" but honestly it mostly just looks strange. Maybe I'm missing something but it seems very surprising to give the two arguments different indentation.
