[Feature Request] - Tabs indent to bracket

When hitting tab on a line, currently, it move the line from 1 tab, i.e.:

```
foo bar (Var1 var1, Var2 var2  
  Var3 var3 {  
}
```

If you want to indent to bracket correctly, you need to bring back the line with var3 on previous line, then hit tab. It would be nice to have line indented to parenthesis when hitting tab from this line.
