[Orgmode] [babel] possible bug in org-babel-execute-buffer?

[Erik Iverson]

Hello,

I am using Emacs 23.1, orgmode pulled from git just an hour ago, but I noticed 
the following issue on a version pulled about a week ago, too.  I don't know if 
it ever worked as I expect.  These development versions have C-c C-v as the 
babel prefix keys, so if you are using a stable version, the following may be 
different.  Also, all my examples use R.

I'm trying to use C-c C-v C-b to call org-babel-execute-buffer, which is 
documented as:

Call `org-babel-execute-src-block' on every source block in
the current buffer.

However, what happens when this is called seems to depend on which trees are 
visible in the buffer when it's called!

Paste the following orgmode file into an org buffer, and make sure all trees are 
fully collapsed, i.e., you just see the headlines "Big Block 1" and "Big Block 
2", and try C-c C-v C-b.

After it's done executing, notice that only the *last* source blocks of each 
tree were run.  Now collapse everything again, and call org-babel-execute-buffer 
again.  The same thing happens, except now there are *two* results present for 
those last code blocks.

Now start all over again with the below code, so no results are present.  Expand 
all subtrees so everything is visible.  Do C-c C-v C-b, and all results are 
inserted as expected.  Run the blocks a second time with everything open, and 
every block still only has 1 results section, as expected.  This is how I would 
expect/hope the function to work regardless of the hide/show states of the trees.

So I think there are two possibly related problems when trees aren't fully 
expanded:

1) Only the last source code block per hidden tree is getting run
2) That last block will insert results multiple times if 
org-babel-execute-buffer is called multiple times

Thanks!
Erik

=================== orgmode code follows below ======================


* Big Block 1
** my first bit of code!
#+begin_src R
 "from the first nested code block in Big Block 1"
#+end_src
** and some more code!
#+begin_src R
  "from the middle nested code block in Big Block 1"
#+end_src
** and final code!
#+begin_src R
  "from the final nested code block in Big Block 1"
#+end_src
* Big Block 2
#+begin_src R
  "from the only code block in Big Block 2"
#+end_src
