"E125 continuation line with same indent as next logical line" in except clause

yapf (tested with 2c13f6f93e8ccfa0c966b67f88eeffe20ccb32a0) turns the following admittedly rather strange code:

```python
try:
pass
except 0 + A(
(lambda: 0), -768, b"\x00\x00\x00\x00\x00\x00\x00\x00", 285873023221760.0
):
pass
```

into the following:

```python
try:
pass
except 0 + A(
(lambda: 0), -768, b"\x00\x00\x00\x00\x00\x00\x00\x00", 285873023221760.0):
pass
```

which causes pycodestyle to complain about the fact that the continuation line starting with the lambda lines up with the pass.

I know pycodestyle isn't generally considered a source of truth for yapf, and pep8 is somewhat ambiguous about what should happen here IMO, but FWIW the former is what [black](https://github.com/ambv/black) produces and definitely seems more in line with how I expect except clauses to be formatted.
