Comment (by nacin):

 So, has_filter() and has_action() only returns the priority when
 $function_to_check is also passed. Otherwise, if you're just checking the
 hook, it returns a boolean.

 In core, we never use the second argument. So, there's no need for us to
 be careful about its use. This is nothing more than a documentation issue.
