On the main page of a course, activity completion progress is reported for each section as "Progress: x / y". This is incorrect where the section contains quizzes requiring a non-zero passing grade as a pass is not counted as a completion.

To reproduce error:
Create a course in topics format, display one section per page, with a section containing one quiz and one url link.
Give the quiz a non-zero passing grade (through the gradebook) and activity completion criteria set to "Student must receive a grade to complete this activity".
For the url set the activity completion criteria to "Student must view this activity to complete it".
Log in as a student.
View the course front page.
The progress indicators for that section shows "Progress 0 / 2"
Enter the section and visit the link and fail the quiz.
View the course front page.
The progress indicators for that section shows "Progress 1 / 2"
Enter the section and pass the quiz.
View the course front page.

WHAT I EXPECTED:
The progress indicator shows "Progress: 2 / 2"

WHAT ACTUALLY HAPPENS:
The progress indicator shows "Progress: 1 / 2"

I think the problem is in renderer.php under course/format.
The offending line appears to count the activities with completion state COMPLETION_COMPLETE but not COMPLETION_COMPLETE_PASS:
if ($completiondata->completionstate == COMPLETION_COMPLETE)
