Will make slug unique, if it isn't already.
The $slug has to be unique global to every taxonomy, meaning that one taxonomy term can't have a matching slug with another taxonomy term. Each slug has to be globally unique for every taxonomy.
The way this works is that if the taxonomy that the term belongs to is hierarchical and has a parent, it will append that parent to the $slug.
If that still doesn't return an unique slug, then it try to append a number until it finds a number that is truly unique.
The only purpose for $term is for appending a parent, if one exists.

// If the taxonomy supports hierarchy and the term has a parent, make the slug unique
// by incorporating parent slugs.
if ( is_taxonomy_hierarchical($term->taxonomy) && !empty($term->parent) ) {
$the_parent = $term->parent;
while ( ! empty($the_parent) ) {
$parent_term = get_term($the_parent, $term->taxonomy);
if ( is_wp_error($parent_term) || empty($parent_term) )

if ( ! term_exists( $slug ) )
return $slug;

// If we didn't get a unique slug, try appending a number to make it unique.
