(Auto-)Indentation of functions not working

New functions, or clauses are indented according to the body of the previous, not the head of it, or base indentation.

Expected behaviour:
```
f1() ->
  herp.
f2() ->
  derp.

```
Actual behaviour:
```
f1() ->
  herp.
  f2() ->
    derp.
```

it does not help to manually invoke auto-indent either.
