Use the comment_as_submitted array for comparing the current comment to the last-seen comment.

The real comment data can be modified/sanitized before it reaches matches_last_comment(), resulting in false negatives -- comments placed in moderation that Akismet has marked as spam.

I've seen it in practice when the email address uses Chinese characters -- something strips them out of the comment passed to matches_last_comment() but not out of the comment we stored in Akismet::$last_comment.
