Subject: 24.3.50; incorrect doc from `C-h f' when use `defadvice' with `before'

emacs -Q
 
Evaluate this sexp:
 
(defadvice query-replace
 (before respect-search/replace-region-as-default-flag activate)
  nil
  (interactive
   (let ((common
          (query-replace-read-args
           (concat "Query replace"
                   (and current-prefix-arg  " word")
                   (and transient-mark-mode  mark-active
                        (not search/replace-region-as-default-flag)
                        " in region"))
           nil)))
     (list (nth 0 common) (nth 1 common) (nth 2 common)
           (and transient-mark-mode  mark-active  (region-beginning))
           (and transient-mark-mode  mark-active  (region-end))))))
 
Then C-h f query-replace.  You see this as part of the description:
 
 :around advice: `ad-Advice-query-replace'
 
1. It should be :before, not :around, no?
(When you click on that link it confirms that it is `Before-advice'.)
 
2. How can you tell where that advice is defined?  It doesn't matter
whether you put that defadvice in a file foo.el and load that.  Neither
C-h f query-replace nor clicking `ad-Advice-query-replace' in that
description tells you anything about where the actual advice
`respect-search/replace-region-as-default-flag' is defined.
