call keywords doesn't unfold * w/o stats

[githubmanticore]

mysql> call keywords('jersey#col*', 'autocomplete_blog_1', 1 as stats); 
+------+-------------+-----------------------+------+------+ 
| qpos | tokenized   | normalized            | docs | hits | 
+------+-------------+-----------------------+------+------+ 
| 1    | jersey#col* | jersey#col*           | 0    | 0    | 
| 1    | jersey#col* | =jersey#columbuspark | 1    | 1    | 
| 1    | jersey#col* | =jersey#columbus      | 1    | 1    | 
+------+-------------+-----------------------+------+------+ 
3 rows in set (0.00 sec) 

works fine, but w/o "1 as stats" it's impossible to see the forms:

mysql> call keywords('jersey#col*', 'autocomplete_blog_1', 0 as fold_wildcards); 
+------+-------------+-------------+ 
| qpos | tokenized   | normalized  | 
+------+-------------+-------------+ 
| 1    | jersey#col* | jersey#col* | 
+------+-------------+-------------+ 
1 row in set (0.00 sec) 

mysql> call keywords('jersey#col*', 'autocomplete_blog_1'); 
+------+-------------+-------------+ 
| qpos | tokenized   | normalized  | 
+------+-------------+-------------+ 
| 1    | jersey#col* | jersey#col* | 
+------+-------------+-------------+ 
1 row in set (0.00 sec) 

The task is to either fix it or update the doc and explain why the current behavior makes sense.
