Duplicate comments should be allowed under different comment_parent
|Reported by:||andy||Owned by:||nacin|
Scenario: A post has several top-level comments. A user treating these as tasks wishes to mark them done by replying to each comment, "Done." The user is forced to vary the "done" reply each time.
Duplicate comment detection prevents accidental re-submission. When comment_parent differs, this probably indicates the user's intention to post the same comment a second time.
