Hi Tassilo,

yes, same here.

Will do.  Most notably, I like the new syntax in macros like \fontspec
et al. where the optional argument comes after the mandatory font name.

Thanks.  While you're on top of font-latex.el game again, can you also
have a look at my proposal here?

    http://lists.gnu.org/archive/html/auctex-devel/2017-04/msg00011.html

On my wish list is also correct fontification for optional and/or
mandatory arguments of math environments, e.g.:

    \documentclass{article}
    \usepackage{amsmath}
    \usepackage[overload]{empheq}
    \begin{document}

    \begin{align}
      a_1 &= b_1 + c_1
    \end{align}

    \begin{empheq}{align}
      a_1 &= b_1 + c_1
    \end{empheq}

    \begin{empheq}[left=\empheqlbrace]{align}
      \label{eq:2}
      a_1 &= b_1 + c_1
    \end{empheq}
    \end{document}

I think the functions `font-latex-match-math-envII' and
`font-latex-extend-region-backwards-math-envII' should be changed for
this.  Right?

Best, Arash
