Those are good points - .r is the extension that I really want as it
would have saved me much frustration trying to figure out why my tests
weren't running.  An alternative would be to report

* checking tests ...
  No test files found

rather than

* checking tests ...
  OK

in the case in which there are no files run in the tests directory.
