Re: Newbie: Custom link type formatting in LaTeX export?

Hi,

This patch (below and attached) seems to fix it. I've put the code at the
end of org-export-latex-links, which seems to be the right place (it doesn't
parallel the organization in the html exporter though).

Please check my work! I'm new to Lisp, and used git for the first time today.

Simple test: Export to LaTeX from an Org file including

[[bbdb:Jane Doe][Ms Doe]]

Currently it defaults to fixed-width (\texttt{Ms Doe}). When patched, it
should come out italicized (\textit{Ms Doe}) as per the export function
in org-bbdb.el.

Yours,
Christian
