Eelco Dolstra 3c92ea399d * Make nix-env --dry-run print the paths to be substituted correctly
again.  (After the previous substituter mechanism refactoring I
  didn't update the code that obtains the references of substitutable
  paths.)  This required some refactoring: the substituter programs
  are now kept running and receive/respond to info requests via
  stdin/stdout.
