When an Essay in a quiz has some general comments, those instructor's comments appear as "Answers" in "Item Analysis Table" when the quiz is reviewed. Tested in 1.8.x and 1.9, both behave the same way (not yet test the 1.7 and 1.6 yet)
Steps to Reproduce
1.) Login as Instructor in latest moodle 1.8 or 1.9.
2.) Create a quiz that has an Essay with some general comments. (feedback)
3.) Login as Student.
4.) Attempt the quiz (the Essay question).
5.) Now, login again as Instructor and review the attempt.
6.) Go to "Item Analysis" Tab & check the "Item Analysis Table".
7.) Check the Essay answer and the general comments.
The General comments on Essay appears in the Answer block. (see screenshot)
What should happen
Only the answers should appear in the answer block and not the comments.
