 we got get_category_parents
 (http://core.trac.wordpress.org/browser/tags/3.1/wp-includes/category-
 template.php#L30)
 which use $parent = &get_category( $id ); limited to 'category' taxonomy,
 but there is nothing similar to other taxonomies. IMO we should rewrite
 this function to be generic and use it as get_term_parents function, the
 existing get_category_parents would use that get_term_parents, so
 something like (sorry, i do not know how to use diff) this:


 {{{
 42      function get_term_parents( $id, $taxonomy, $link = false,
 $separator = '/', $nicename = false, $visited = array() ) {
 43              $chain = '';
 44              $parent = &get_term( $id, $taxonomy );
 45              if ( is_wp_error( $parent ) )
 46                      return $parent;
 47
 48              if ( $nicename )
 49                      $name = $parent->slug;
 50              else
 51                      $name = $parent->name;
 52
 53              if ( $parent->parent && ( $parent->parent !=
 $parent->term_id ) && !in_array( $parent->parent, $visited ) ) {
 54                      $visited[] = $parent->parent;
 55                      $chain .= get_term_parents( $parent->parent,
 $link, $separator, $nicename, $visited );
 56              }
 57
 58              if ( $link )
 59                      $chain .= '<a href="' . get_term_link(
 $parent->term_id ) . '" title="' . esc_attr( sprintf( __( "View all posts
 in %s" ), $parent->name ) ) . '">'.$name.'</a>' . $separator;
 60              else
 61                      $chain .= $name.$separator;
 62              return $chain;
 63      }
 }}}
 and
 {{{
 function get_category_parents( $id, $link = false, $separator = '/',
 $nicename = false, $visited = array() ) {
    return get_term_parents ($id,'category',$separator,$nicename,$visited);
 }
 }}}
