So it turns out the attempted fix for CVE-2013-2009 was incomplete. To
quote reddit:

"Erm, you forgot about escaping markdown metachars. Here, the fixed
version, edit it in: \*\^_\^\*"

http://www.reddit.com/r/netsec/comments/1czzyx/update_wp_super_cache_and_w3tc_immediately_remote/c9lvxn8

And to quote the WP-Super-Cache 1.3.2 ChangeLog:

+= 1.3.2 =


+* Any mfunc/mclude/dynamic-cached-content tags in comments are now
removed.

So please use CVE-2013-2011 for this issue.

NOTE: this issue exists because of an incomplete fix for CVE-2013-2009.
