Subject: [PATCH] ox-latex: convert verbatim text in headings to tt
* lisp/ox-latex.el (org-latex-format-headline-default-function): Convert
any instances of \verb text with \texttt. This is required to work
around LaTeX peculiarities that would otherwise cause compilation to
fail (see the code comment for more information).
