Bug: org-meta-return in narrowed buffer makes the last line invisible

[Yasushi SHOJI]

Hi,

In my current environment, org-meta-return seems to make the last line
of a buffer invisible if the buffer is narrowed.  At first I thought
the lines are gone but that was false.  All text are there but you
can't see it.

First, here is my environment:

 - Org-mode version 8.0.3 (release_8.0.3-150-g61d8eb @ /home/yashi/src/org-mode/lisp/)
 - "GNU Emacs 24.3.1 (x86_64-pc-linux-gnu, GTK+ Version 3.4.2) of
   2013-04-14 on trouble, modified by Debian"
 - uname -a: Linux leno 3.8-2-amd64 #1 SMP Debian 3.8.13-1 x86_64 GNU/Linux
 - Debian Sid


Second, here is my step to reproduce:

 1. create a file with the following lines:
     #+BEGIN_SRC org
       ,* head
       ,** the last line in the narrow
       ,* the last line
     #+END_SRC
 2. emacs -Q
 3. open the above file
 4. narrow the buffer at 'head' with org-narrow-to-subtree
    to make the contents as below:
     #+BEGIN_SRC org
       ,* head
       ,** the last line in the narrow
     #+END_SRC
 5. org-meta-enter at the end of the first line.
    this makes the visible contents to be
     #+BEGIN_SRC org
       ,* head
       ,** the last line in the nar
     #+END_SRC

     notice that "narrow" became "nar"


Is this reproducible?  Does anyone see this bug?

Thanks,
