Dear Orgmode maintainers,
I would like to provide a patch which allows nested emphasis
for the latex export. The problem of handling nested emphasis
was solved by applying the org-export-latex-fontify recursively.
The example
Now *you /can/ write* /nested/ */emphasis/ recursively!*
will be translated to:
Now \textbf{you \emph{can} write} \emph{nested}
\textbf{\emph{emphasis} recursively!}
Best regards, yours faithful
Robert Hennig
