"Single line" def which spans multiple lines compiled incorrectly

``` cheetah
#def f(
    x,
): bar
```

Is compiled to (simplified):

``` python
def f(self, x):
    # No contents

def respond(self):
    write('bar')
```

I expect:

``` python
def f(self, x):
    write('bar')

def respond(self):
    # No contents
```
