commit 3ef28a55e3671b078c2042d0620c45c973216684
Author: Arash Esbati <arash@gnu.org>
Date:   Tue Jul 28 22:00:32 2020 +0200

    Add an extra check for tex-buf.el in some style hooks
    
    * style/arabxetex.el ("arabxetex"):
    * style/bidi.el ("bidi"):
    * style/fontspec.el ("fontspec"):
    * style/polyglossia.el ("polyglossia"): Check if "tex-buf.el" is
    loaded and require it otherwise.  `TeX-check-engine-add-engines'
    is defined in "tex-buf.el" and the hook would exit too early if
    the library isn't loaded.
