Quelle est la séquence correcte pour charger un schéma de couleurs dans votre fichier .vimrc ?

J'ai trouvé cet extrait dans zenburn.vim .

" * Work-around to a Vim bug, it seems to misinterpret ctermfg and 234 and 237            
"   as light values, and sets background to light for some people. If you have            
"   this problem, use:                                                                    

"   let g:zenburn_force_dark_Background = 1        

if exists("g:zenburn_force_dark_Background")
    " Force dark background, because of a bug in VIM:  VIM sets background
    " automatically during "hi Normal ctermfg=X"; it misinterprets the high
    " value (234 or 237 above) as a light color, and wrongly sets background to
    " light.  See ":help highlight" for details.
    set background=dark
endif

Pour corriger cela, il suffit d'ajouter

set background=dark

à la fin de desert256.vim après toutes les mises en avant.
