Hello,

Here is a patch making latex exporter smarter about lists.

Here is a (vicious) example of what can be exported now.

------------------------------------------------------------------
  1. A very long line with a mathematical environment at its end \(x =
     25 \)

     #+BEGIN_EXAMPLE
  3. three
  4. four
     #+END_EXAMPLE

  2. Another line
------------------------------------------------------------------

Exporting to html is still a problem though : it doesn't seem to use
org-list-to-html (and thus org-list-parse-list) from org-list.el.
