Super indent when editing R blocks and using a # comment

Find attached a screenshot of the behavior I'm experiencing with this
minimal config and =emacs -Q=.

#+begin_src min-config

;; set load paths
;; set load dirs and global config options
(add-to-list 'load-path "~/.elisp/org.git/lisp/")
(add-to-list 'load-path "~/.elisp/org.git/contrib/lisp")
(add-to-list 'load-path "~/.elisp/ess/lisp/")

(require 'ess-site)

;; setup babel languages
(org-babel-do-load-languages
 'org-babel-load-languages
 '((R . t)))

#+end_src

As shown in the shot:
- create a .org file, insert a #+begin/end_src R block
- edit with =C-c '=
- start a line with a comment char (#)
- press RET
- it gets indented halfway across the page

Inside a function, it seems to use a default of four spaces (the
position of =return(i^2)=), so I'm not sure why a comment triggers
such a massive indent. I end up having to delete the preceding spaces
or be super careful about having a newline already inserted so that I
can arrow down instead of pressing RET at the end of a comment line.


Thanks for any insights!
John
