 I want to create links like such: "Add a new post with tag X" with a URL
 like this: wp-admin/post-new.php?new_tag=X

 Clicking on the link would take you to the Add New Post admin panel with
 tag X already added.

 Unfortunately, there is no clean way for a plugin to make this work. The
 only clean way would be to add a filter on 'terms_to_edit' which adds the
 new_tag var to the end of the terms.

 Unfortunately, get_terms_to_edit() returns early if there is no post ID
 and never reaches the necessary filter:


 {{{
 function get_terms_to_edit( $post_id, $taxonomy = 'post_tag' ) {
         $post_id = (int) $post_id;
         if ( !$post_id )
                 return false; // <------ BAILS OUT EARLY HERE

         $tags = wp_get_post_terms($post_id, $taxonomy, array());

         if ( !$tags )
                 return false;

         if ( is_wp_error($tags) )
                 return $tags;

         foreach ( $tags as $tag )
                 $tag_names[] = $tag->name;
         $tags_to_edit = join( ',', $tag_names );
         $tags_to_edit = esc_attr( $tags_to_edit );
         $tags_to_edit = apply_filters( 'terms_to_edit', $tags_to_edit,
 $taxonomy );   // <-------- THE FILTER I NEED TO HOOK ONTO TO ADD MY NEW
 TAG

         return $tags_to_edit;
 }
 }}}

 So, a possible solution would be to still apply the filter when bailing
 out on an empty post_id.
