Browsing RealWorld broken

Here is another one: the case for foreign declarations seems to miss
in ghc/compiler/ghci/InteractiveUI.hs:showDecl:

> ./bin/ghci
   ___         ___ _
  / _ \ /\  /\/ __(_)
 / /_\// /_/ / /  | |      GHC Interactive, version 6.3, for Haskell 98.
/ /_\\/ __  / /___| |      http://www.haskell.org/ghc/
\____/\/ /_/\____/|_|      Type :? for help.
