Displays [[nid:123]] if node 123 isn't displayable because of permissions (Content access)

I have a download page which has some public downloads on it then some private downloads underneath. The way I'm controlling who can access private downloads is to make it its own node, use content access to make it so only a certain role can view the node, private files control access via the node, and then I embed that node in the main download node to make it so I get a private section that opens up for the right users and not for others. Everything works - except for users which can't access the node, the filter just spits back the [[nid:123]] tag where it should really not print anything at all and I think that's the desired behavior. I'll live with this artifact on the site for today but I would really appreciate the little patch to make it so when there's no permission, it doesn't print the tag.

Thanks!
