 The global var ''$pagenow'' will be evaluated at all versions using the
 '''vars.php''' ''else'' path (non admin pages).
 But this is the wrong place. It's only possible to set the correct
 processed page (template file name) at the '''template-loader.php''' after
 evaluation of correct template file!

 In my opinion there should be a function inside the ''template-
 loader.php'' like:

 {{{
 function redefine_pagenow($template) {
         global $pagenow;
         if ( preg_match('#([^/]+\.php)([?/].*?)?$#i', $template,
 $self_matches) )
                 $pagenow = strtolower($self_matches[1]);
         else
                 $pagenow = 'index.php';
 }
 }}}

 and the ''if/else'' cascades should use the function for redefine the
 correct template file been processed currently as frontend view (example
 excerpt):


 {{{
 ...
         } else if ( is_single() && $template = get_single_template() ) {
                 redefine_pagenow($template);
                 include($template);
                 return;
         } else if ( is_page() && $template = get_page_template() ) {
                 redefine_pagenow($template);
                 include($template);
                 return;
         } else if ( is_category() && $template = get_category_template())
 {
                 redefine_pagenow($template);
                 include($template);
                 return;
 ...
 }}}

 This will permit theme/template designer to detect using the correct
 ''$pagenow'' var what template is been currently processed instead of
 always ''index.php''

 This problem is also related to older versions of WordPress.
