  * Use the given working dir when preparing to call setup
  I introduced a subtle bug with paths when I stopped using inDir
  outside of setupWrapper. It was using the current dir to find
  Setup.hs rather than the target dir. That ofen works because
  there's a Setup.hs in the local dir. I think it's now fixed to
  always use paths relative to workingDir. As before, it invokes
  the setup binary giving it the new working dir.

    M ./Distribution/Client/SetupWrapper.hs -7 +11
