## What went wrong

g:ale_python_yapf_options not in effect.

## Reproducing the bug

1. test file content:

```python
def flist(l=[1]):
l.append(1)
print(l)
a = [1, 2, 3, 4, 4, 5, 6, 6, 6, 76, 56, 54, 4, 34, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 2, 3, 4, 5, 6, 7, 8, 1, 2, 4, 4, 4]

flist()
flist()

def sum_two_num(x, y):
"""add two num"""

return x + y

print("测试")

print(sum_two_num(1, 2))
```

Correct formatted text:

```python
E:\>yapf --style "{based_on_style: pep8, column_limit: 120}" E:\test2.py
def flist(l=[1]):
l.append(1)
print(l)

a = [1, 2, 3, 4, 4, 5, 6, 6, 6, 76, 56, 54, 4, 34, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 2, 3, 4, 5, 6, 7, 8, 1, 2, 4, 4, 4]

flist()
flist()

def sum_two_num(x, y):
"""add two num"""

return x + y

print("测试")

print(sum_two_num(1, 2))

```

The result with ALEFix:

```python
def flist(l=[1]):
l.append(1)
print(l)

a = [
1, 2, 3, 4, 4, 5, 6, 6, 6, 76, 56, 54, 4, 34, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4,
2, 3, 4, 5, 6, 7, 8, 1, 2, 4, 4, 4
]

flist()
flist()

def sum_two_num(x, y):
"""add two num"""

return x + y

print("测试")

print(sum_two_num(1, 2))
```

----

You see that I set `let g:ale_python_yapf_options = '--style "{based_on_style: pep8, column_limit: 120}"'`, but it still use default max line length 80.
