[Tassilo Horn]

branch: externals/auctex
commit 7209776eddeee0d01adf8f72ba4b5495c4bb7542
Author: Arash Esbati <address@hidden>
Commit: Arash Esbati <address@hidden>

    Skip macros and environments from tcolorbox and raster library
    
    * tex-ispell.el (TeX-ispell-sort-skip-cmds-list): Extract macros
    with optional argument from `TeX-ispell-skip-cmds-list'.
    (TeX-ispell-skip-cmds-opt-arg-regexp): New variable containing
    macros where only the optional argument is skipped while spell
    checking.
    Add macros and environments from tcolorbox.el and
    tcolorboxlib-raster.el.
