Update to 0.042
    
    - New upstream release 0.042
      - When 'realpath' can't be resolved (because intermediate directories don't
        exist), the exception now explains the error clearly instead of complaining
        about path() needing a defined, positive-length argument
      - On Windows, fixed resolution of relative paths with a volume, e.g. "C:foo"
        is now correctly translated into getdcwd on "C:" plus "foo"
