User's guide PDF version: Example with wrong indentation in Section 13.1.1.2

In the pdf version of User's Guide Version 7.10.1, the first example of "Section 13.1.1.2 Contex-free syntax" has the following wrong indentation:

main = do args <- getArgs
    if null args then return [] else do
          ps <- mapM process args
          mapM print ps

The HTML version is OK, though.
