orgstruct: broken global visibility cycling, when in comments

I'm attempting to use orgstruct minor mode in emacs-lisp-mode (org 8.0.3 in
recent Aquamacs and in vanilla Emacs 24.3.1).  I find:
- cycling an individual headline using tab key works fine
- global cycling via S-Tab (when on a headline) to more expanded visibility
(e.g. OVERVIEW --> CONTENTS or CONTENTS --> SHOW ALL) works fine
- global cycling via S-Tab (when on a headline) to more limited visibility
fails without error (echo area still reports OVERVIEW or CONTENTS, etc.)

I have orgstruct-heading-prefix-regexp set to "^;;".
Example buffer contents that fail global cycling to narrower scope:

;; Testcase for orgstruct-mode in emacs-lisp-mode
;;* top level headline 1
;;** 2nd level headline A
(setq var2 "value2")
;;** 2nd level headline B
(setq var3 "value3")
;;** 2nd level headline C
(setq var4 "value4")
;;* top level headline 2
(setq var5 "value5")

I find no trouble with global cycling if I remove the ";;" comment
characters in all headlines and set orgstruct-heading-prefix-regexp to nil.

I suspect this is a bug; but perhaps I'm doing something wrong?  Thanks for
any help.

Cheers,
Nathaniel

does it work with "^;;[*]+ " ?

Does setting orgstruct-heading-prefix-regexp to ";;" make a difference?

Note that this value for the prefix (actually the version with a space,
"^;; ") is suggested by the Org manual for version 8.0.3

Christopher pointed out that "orgstruct-mode implicitly starts the real
regexp that is used for headline matching with a ^.  Your additional ^
breaks the regexp."
I verify that setting orgstruct-heading-prefix-regexp to ";;" (or ";; "
with a space) solves the problem.

Thank you Christopher!

I fixed the manual.  Thanks for reporting this!
