master bfc4393040: Include nil as valid wallpaper-commmand

[Mattias Engdegård]

branch: master
commit bfc4393040037a3dd17531e6e9dcfa6990a3c33d
Author: Mattias Engdegård <mattiase@acm.org>
Commit: Mattias Engdegård <mattiase@acm.org>

    Include nil as valid wallpaper-commmand
    
    * lisp/image/wallpaper.el (wallpaper-command):
    Include nil in the type since that is a valid value for the variable,
    and may be the default value.  This should fix test-custom-opts.
