Re: Org Haskell code blocks

[Dominik Schrempf]

I apologize, the settings described in Point 1 actually have no effect.
Multi line input works out of the box (at least with "ghci" as
described). However, the result output is still scrambled (e.g., empty
lines, unnecessary "ghci>" prompts in results)
