New validate failures

[Johan Tibell]

Hi,

Did something change in pretty-printing recently? I saw these new validate
failures today:

Unexpected failures:
   ghci.debugger/scripts  break008 [bad stdout] (ghci)
   ghci.debugger/scripts  break012 [bad stdout] (ghci)
   ghci.debugger/scripts  break026 [bad stdout] (ghci)
   ghci.debugger/scripts  hist001 [bad stdout] (ghci)
   ghci/scripts           T5545 [bad stdout] (ghci)
   ghci/scripts           ghci008 [bad stdout] (ghci)

   ghci/scripts           ghci023 [bad stdout] (ghci)

   ghci/scripts           ghci026 [bad stdout] (ghci)
   ghci/scripts           ghci055 [bad stdout] (ghci)

Two example stdout changes:
