branch: externals/auctex
commit 324cb5c9134ae2ed974fa58a6584424c899e7289
Author: Arash Esbati <arash@gnu.org>
Commit: Arash Esbati <arash@gnu.org>

    Simplify implementation of style/hologo.el
    
    * style/hologo.el
    (LaTeX-hologo--arg-use-region-or-query-logo-name): Reduce
    functionality.
    (LaTeX-hologo--arg-use-region): New helper function to wrap region
    in a pair of braces.
    ("hologo"): Use new functions in combination with
    `TeX-arg-conditional'.
    Replace `TeX-arg-eval'.
