[O] LaTeX export: inline markup underscore problem

[Mauro Rovezzi]

Dear all,

I implemented the inline markup for latex export as suggested on Worg
by Tom Dye:

http://orgmode.org/worg/org-tutorials/org-latex-export.html#sec-10_3

and I have a big problem in exporting references with underscores.
Example: [[latex:cite][some_thing]] is rendered by the latex exporter
as \cite{some\_thing} that is bad because will result in a broken
reference. Could you help me in defining a more clever
org-add-link-type?

Thanks,
Mauro
