>     * lisp/org-exp.el (org-export-define-heading-targets): Currently,
>     the section number (a string of the form "X.Y.Z") is used to
>     manufacture a section label of the form sec-X_Y_Z. Underscores are
>     overloaded however, both in org and in LaTeX, and cause conflicts
>     with some packages. This patch changes underscores to hyphens in
>     section labels.
