 In {{{wp-include/vars.php}}} an unset variable is passed by referecence to
 {{{preg_match()}}} in mutliple places.

 The same code-fragment where that problem is located does poisen the
 globale variable table with temporary variables as well.

 To prevent these problems, the variable needs to be set prior to be passed
 to preg_match and the code fragment needs to be refactored in it's own
 function.

 This might be helpful a bit as well when we start to free the codebase
 from hardencoded {{{/wp-admin/}}} admin directory definitions.
