Comment(by deadowl):

 I updated the content_tags.php file to a version that factors out the
 global variable, as well as the last remaining look-around assertion.

 The method employed will prevent certain patterns from being parsed, but
 they wouldn't likely be widespread. What happens is that it will parse
 something that looks like a valid shortcode, ignoring the name, and then
 if the name doesn't have a hook, it will just output the original
 expression.

 "so if [this content tag] is invalid" would then translate to "so if is
 [this content tag] is invalid" given the tag "this" not having a hook.

 The implementation prevents certain syntax variations.

 ex 1.
 [invalid-tag hello="[valid-tag/]"], the inline-expression, [valid-tag/],
 is not interpreted

 ex 2.
 [invalid-tag]], the escaped right-square-bracket is not interpreted

 Another option would be to swallow tags that don't have a callback. My
 main concern here is keeping the syntax intuitive. Any feedback?
