    Simplify ef-themes-collection (thanks Philip Kaludercic)
    
    Thanks to Philip for suggesting the use of 'seq-union' over at the
    emacs-devel mailing list:
    <https://lists.gnu.org/archive/html/emacs-devel/2022-09/msg01053.html>.
    
    I could not use 'seq-union' because it introduces a dependency on Emacs
    28.  I went with 'append' instead.
