There should be no functional difference, except that the error message
is changd from "three or no arguments" to "zero or three arguments". Somehow
the inverted form always seemed strange.
umask() call is also dropped from run-generator. I think it wasn't dropped in
053254e3cb because the run generator was merged
around the same time.
