[elpa] externals/auctex b866110 31/71: Autoload `TeX-check-engine-add-engines' in tex.el

[Tassilo Horn]

branch: externals/auctex
commit b8661101b955c7c62a79a696893a50da3450dde2
Author: Arash Esbati <arash@gnu.org>
Commit: Arash Esbati <arash@gnu.org>

    Autoload `TeX-check-engine-add-engines' in tex.el
    
    * style/arabxetex.el ("arabxetex"):
    * style/babel.el ("babel"):
    * style/bidi.el ("bidi"):
    * style/fontspec.el ("fontspec"):
    * style/polyglossia.el ("polyglossia"): Don't require tex-buf.el
    in the style hook.
    
    * tex.el (TeX-check-engine-add-engines): Autoload the function so
    the styles using it don't have to require tex-buf.el.
