[elpa] externals/auctex fcaef6b 11/80: Improve fontification of \href macro

[Tassilo Horn]

branch: externals/auctex
commit fcaef6bab89e6a629d60f1b43038a2433e34fbd5
Author: Arash Esbati <address@hidden>
Commit: Arash Esbati <address@hidden>

    Improve fontification of \href macro
    
    * style/hyperref.el ("hyperref"): Add "href" to
    `LaTeX-verbatim-macros-with-braces-local'.
    Check for feature font-latex and not for functions.
    Declare and use `font-latex-update-font-lock' instead of
    `font-latex-set-syntactic-keywords'.
