haddock recognizes the following file, but cabal haddock doesn't recognize it.

blabla, blibli
$a+b$
\begin{code}
main=putStrLn "Hello"
\end{code}

If Haddock recognises it but cabal haddock doesn't then it's a problem with how cabal invokes Haddock. Please file a bug with cabal folks.

Here's a re-formatted example for reference.

blabla, blibli
$a+b$
\begin{code}
main=putStrLn "Hello"
\end{code}

Feel free to re-open if you disagree.
