How-to get the get_category_parents() breadcrumbs trail without link on last item

I wouldn’t consider this any better/worse than Kaiser’s option, but just different. Why not use get_category_parents on the parent category and then (optionally) append the current category?

I haven’t tested this, but something like the following should work:

$cat_id=7;//current category's ID (e.g. 7)
$separator="&raquo;";//The separator to use
$category = get_category($cat_id);//$category is the current category object
$parent_id = $category[0]->category_parent //category's parent ID
$ancestors = get_category_parents($parent_id, true, $separator);

Then optionally add the current category’s name:

 if($ancestors){
      $breadcrumb = $ancestors.$separator.' <span class="active-cat">'.single_cat_title().'</span>';
 }else{
      $breadcrumb = '<span class="active-cat">'.single_cat_title().'</span>';
 }
     echo $breadcrumb;

EDIT:

It turns out this almost exactly how WordPress produces the output: get_category_parents calls itself recursively (see here), so with this method you are essentially ‘stopping it early’, and manually completing it. There are no hooks that can achieve this effect however.

EDIT:
