[O] [BUG] in LaTeX export

[Thomas Holst]

Hello,

while exporting an org-file to LaTeX I stumbled across a minor bug with
emphasis and underscores.

Minimal org-file:
#+begin_src org
#+OPTIONS: ^:{}
* Emphasis Test

  _abc /_abc/ *_abc* /a_bc/ *a_bc*

#+end_src

leads to the following LaTeX code:

#+begin_src

  \_{}abc \emph{_abc} \textbf{_abc} \emph{a\_{}bc} \textbf{a\_{}bc}

#+end_src

So emphasised text strings starting with an underscore are not exported
correctly and confuse LaTeX.

emacs 23.2 on WinXP, org-mode version 7.5 (release_7.5.34.g54c51)
(localy patched Makefile and org-git-link.el)

Best regards
  Thomas

P.S. org-mode is a superb piece of software and really makes my life
a lot easier. Thanks to all of you!
