[Haskell-cafe] Layout rules for if then else

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?
