I am working on ghc-exactprint, and need to flag points where layout must be preserved, and considering the `if` statement.

My understanding of the layout rules for if then else is that the `then` has to start more to the right than the `if`.

Using GHC 7.10 RC2, ghci cheerfully loads the following

```
f =
if True
then 1
else 2

```

Is this valid? Have the rules been relaxed?
