PEP8 indentation can be either of the following forms (but not mixed together):

```python
raise Exception("foofoofoofoo "
                "foofoofoofoo.") # aligned with opening paren
```

or

```python
raise Exception(
    "foofoofoofoofoofoofoofoo " # all lines indented with 4 spaces
    "foofoofoo.")
```

Can you please fix the indentation here and throughout the code? I noticed this in a few places.
