210,.lhs Birdtracks are removed instead of replaced,pesco,nobody,"{{{
With respect to Bird-style literate programs, the
Report states in section 9.4 (p. 134) that ""[t]he
program text is recovered by taking only those lines
beginning with '>', and replacing the leading '>' with
a space.""
The following program seems to indicate that GHC strips
the leading '>' instead:

-----mixed.lhs-----
\begin{code}
  -- Notice two leading spaces!
  main = putStrLn ""This is LaTeX-literal Haskell.""
\end{code}

> main = putStrLn ""This is Birdtrack-literal Haskell.""
------------------------

GHC says ""mixed.lhs:5: parse error on input `main'""
instead of ""Multiple declarations of `Main.main'"".
Inserting a second space after the '>', however, yields
the latter.

I just stumbled across this because I'm writing a
syntax highlighter and the Report only advises against
but does not forbid mixed-style literate programs.
