QSettings in style kcm

[Carlo]

Hi,
i've noticed that the style kcm use QSettings instead of kconfig to
save some effect preferences
http://lxr.kde.org/source/KDE/kdebase/workspace/kcontrol/style/kcmstyle.cpp#619
I don't think it's right since if i use systemsettings the filename is
~/.config/kde.org/systemsettings.conf while if i use kcmshell4 the
filename is ~/.config/kde.org/kcmshell.conf
