Part of the problem is that haskell-mode appears to use non-standard
prompt:

comint-prompt-regexp: ^[[:alnum:].*_() |λ]*> \|^λ?>
Output: ghci| ghci| ghci| ghci| ghci| 6

Note "|".

We may want to either report this upstream or modify
`org-babel-interpret-haskell' further where it extends
`comint-prompt-regexp'.

On my system, the output contains different number of spaces in
"[a]<spaces>-- ". It appears to be system-dependent. Looks like test's
fault.
