Thanks for guiding new contributors with an easy to understand example.

And if the fix is simple enough (i.e. a good rule of thumb is if the
fixes themselves without tests need to be multi-patch series, it is
not simple enough), have a single patch that has both fix and test
that expects success, instead of splitting them into two to make a
two patch series whose first step expects a failure and whose second
step fixes and flips failure to success.
