    Import emblem-new from Adwaita
    
    Emblems are considered deprecated since GNOME 3.32:
    https://gitlab.gnome.org/GNOME/adwaita-icon-theme/-/commit/7f3f91f9c210ee240885c7d370c8ff3485c3a17b
    and `emblem-new` has been removed in GNOME 42:
    https://gitlab.gnome.org/GNOME/adwaita-icon-theme/-/commit/becf0674bb631bb2f2e092e1fb0f4d55cf380de7
    
    This will cause Meld to complain loudly on vanilla GNOME, even breaking the file tree view:
    
            Traceback (most recent call last):

    `emblem-default-symbolic` and `emblem-symbolic-link` are still available.
    
    Let’s bundle it with Meld as suggested.
