    latex: fix headings with curly braces inside them
    
    The headings are delimited by the opening and closing curly braces. But
    they can contain other latex commands inside them, for example:
    \section{\LaTeX{}ila}
    \section{\textit{italic} normal}
    
    And the curly braces pairs can be nested:
    \section{\textit{foo \textbf{bar}}}
