[Orgmode] Overlays and elisp code

[Andrea Crotti]

I found a strange behaviour which might be a bug, but maybe of my
configuration.

This is org mode version:
Org-mode version 7.4 (release_7.4.199.g8be1.dirty)
and emacs:
"GNU Emacs 23.2.1 (x86_64-apple-darwin10.3.0, NS apple-appkit-1038.29)
 of 2010-05-09 on linc"

To reproduce the bug I do
- go over an elisp code block
- C-c ' to edit in the overlay
- C-c ' to go back when done

And it works perfectly, BUT if for example I remove a parenthesis before
pressing C-c ', I can't go back.

C-c ' becomes undefined and I have to kill both the overlay and the
original buffer.

While I was writing I also found the cause of the problem, Paredit!
Removing the hook from emacs-lisp-mode-hook fixes this, but paredit is
really useful with elisp, maybe someone has an idea of why this happens?
