spanning multiple lines detection

In progress but here are the effects so far
```

if ( a == b
    && c == d
    && e == f
    || g == h
    || i == j ) {
  a = b
    + c
    - d;
}
```
as opposed to this which would indent everything following it:
```

if ( a == b
    && c == d
    && e == f
    || g == h
    || i == j ) {
  a = b
    + c
    - d;
    }
```
