[Tassilo Horn]

branch: externals/auctex
commit 08f5c9e4c96e78806344fe26294ea2fe7158cee8
Author: Arash Esbati <arash@gnu.org>
Commit: Arash Esbati <arash@gnu.org>

    Improve handling of key=vals in style/floatrow.el
    
    * style/floatrow.el (LaTeX-floatrow-key-val-options-local)
    (LaTeX-floatrow-update-key-val-options): Remove now unused
    variable and function.
    (LaTeX-floatrow-key-val-options): New function returning key=vals.
    (LaTeX-floatrow-auto-cleanup)
    (LaTeX-floatrow-arg-declare-new-options): Remove call of
    `LaTeX-floatrow-update-key-val-options'.
    ("floatrow"): Call the function `LaTeX-floatrow-key-val-options'
    instead of the variable `LaTeX-floatrow-key-val-options-local'.
    Minor spacing fixes.
