    I've seen in the archives that Dieterbe had created a `dmenu` Git
repository mirror on GitHub, and as I'm more inclined towards Git than
to Hg, I've cloned his repository and created a branch for the
before-mentioned patch (see below the branch and the two patches that
do what I've described previously):

    So thanks Dieterbe for the repository clone.
