[O] BUG: beamer export and overlay specifications for nested list

[Andreas Leha]

Hi all,

there seems to be a bug that becomes apparent when overlay
specifications are given to items in sublists.

Here is an example:

--8<---------------cut here---------------start------------->8---
#+TITLE: Example Presentation
#+AUTHOR: Carsten Dominik
#+OPTIONS: H:2
#+LATEX_CLASS: beamer
#+LATEX_CLASS_OPTIONS: [presentation]
#+BEAMER_THEME: Madrid
#+COLUMNS: %45ITEM %10BEAMER_ENV(Env) %10BEAMER_ACT(Act) %4BEAMER_COL(Col) 
%8BEAMER_OPT(Opt)

* This is the first structural section

** Frame 1

- @@beamer:<1->@@ First Item
  - @@beamer:<address@hidden>@@ First Subitem
  - @@beamer:<address@hidden>@@ Second Subitem
- @@beamer:<3->@@ Second Item
--8<---------------cut here---------------end--------------->8---


And the relevant part of the exported tex file:

--8<---------------cut here---------------start------------->8---
\begin{itemize}
\item<1-> First Item
\begin{itemize}
\item<1-><address@hidden> First Subitem
\item<1-><address@hidden> Second Subitem
\end{itemize}
\item<3-> Second Item
\end{itemize}
--8<---------------cut here---------------end--------------->8---


This should be:

--8<---------------cut here---------------start------------->8---
\begin{itemize}
\item<1-> First Item
\begin{itemize}
\item<address@hidden> First Subitem
\item<address@hidden> Second Subitem
\end{itemize}
\item<3-> Second Item
\end{itemize}
--8<---------------cut here---------------end--------------->8---
