      Right now if your pipeline script inadvertently tries to invoke the sh step, something approximating this error will fail your build:

Finished: FAILURE

      I expect the build to error out, but something more helpful would be nice, like "The `sh` step is not supported on the Windows platform, please use `bat` or install Cygwin"
