[Haskell] Hyperlinking problem in Haddock

Hello, Does anybody know how you hyperlink your Haddock to functions whose name ends with a prime. e.g. foldl' I've tried.. 'foldl\'' and 'foldl'' But neither works. In each case I get a link to foldl (unprimed version) followed by an isolated ' character. This is with Haddock version 0.6 BTW. Thanks -- Adrian Hey
