unlit/ghci does not work on DOS file

Hi, calling unlit on a DOS file fails, whereas hugs is able to process the same file (under unix). Christian Prelude> readFile "Test.lhs" >>= putStrLn . show "\r\n> module Test where\r\n>\r\n" Prelude> :l Test.lhs Test.lhs line 2: unlit: Program line next to comment phase `Literate pre-processor' failed (exitcode = 1)
