Description

Cabal mangles exceptions, e.g.: 

$ "utils/ghc-cabal/dist/build/tmp/ghc-cabal" install "/home/ian/ghc/git/ghc/bindisttest/install dir/lib/ghc-7.1.20110421/ghc" "/home/ian/ghc/git/ghc/bindisttest/install dir/lib/ghc-7.1.20110421/ghc-pkg" ":" "/home/ian/ghc/git/ghc/bindisttest/install dir/lib/ghc-7.1.20110421" libraries/ghc-prim dist-install '' '/home/ian/ghc/git/ghc/bindisttest/install dir' '/home/ian/ghc/git/ghc/bindisttest/install dir/lib/ghc-7.1.20110421' '/home/ian/ghc/git/ghc/bindisttest/install dir/share/doc/ghc/html/libraries'
Installing library in /home/ian/ghc/git/ghc/bindisttest/install
dir/lib/ghc-7.1.20110421/ghc-prim-0.2.0.0
ghc-cabal: /home/ian/ghc/git/ghc/bindisttest/install
dir/lib/ghc-7.1.20110421/settings: openFile: does not exist (No such file or
directory)

where a space in the filename has been replaced with a '\n'. This can be very confusing!

It looks like Distribution.Simple.Utils.topHandler / wrapText is the culprit.
