			These should be now just 1 for all three tests,
			since it is the actual number of the test not
			position in the test data array, I guess that we
			may pass that in $3 if ever needed.

Shouldn't this now be?

# test 1 TPASS: Test 1 passed with data 'foo'
# test 2 TPASS: Test 2 passed with data 'foo'
# test 1 TPASS: Test 1 passed with data 'bar'
# test 2 TPASS: Test 2 passed with data 'bar'

						      This is no longer
						      true right?

Shouldn't we prefix these two variables with _tst_ prefix as well?
