Parse +1's into Recent Activity macro

Lots of comments on EAC are +1's or some variant. In the Recent Activity macro, below the post title and right of the author information, some text from the post or comment is displayed. However, plus symbols are filtered out of the text in the Recent Activity macro, so it just displays a user's +1 comment as "1" plus whatever the author writes after that. It would be nice if the comment displayed correctly in the macro.
