    Take care of `unload-feature'
    
    * tex-site.el.in (tex-mode): Deactivate form registered by
    `with-eval-after-load' if `tex-site' is unloaded.
    (): Delete unnecessary codes.  Current code puts `defalias' rather
    than `autoload' in tex-site.el for `plain-TeX-mode' and `LaTeX-mode'
    by "###autoload" cookies.
