I think what's happening is that users happen to have an external copy of `diff` that gets called when it appears in a pipeline, or they are prefixed by `not`. The external `diff` is called, and things "work out" and we never noticed.


Are these patches going to break those tests on Windows?  We now see `diff` anywhere in a pipeline, and we reject its appearance in a pipeline.
