broken source link

Hi, when trying to look up the original definition for Data.List.transpose in https://downloads.haskell.org/~ghc/latest/docs/html/libraries/Data-List.html I found that the source link https://downloads.haskell.org/~ghc/latest/docs/html/libraries/src/Data-OldLi... does not work. Could this be fixed? Or should I look elsewhere for the sources? Cheers Christian P.S. my looking up transpose was inspired by https://mail.haskell.org/pipermail/haskell-prime/2015-March/003933.html
