Indentation in multiline condition.

I assume that in the case of a condition, it is better to align to condition on previous line.
I think this code:
```
if a + b > 0 && ...
a * b > 0
a = b;
end
```
better than generated by MBeautifier:
```
if a + b > 0 && ...
a * b > 0
a = b;
end
```

So, this is true for `while` too.
