 Hmm, I'm sorry for my ignorance, I was completely wrong. Let me correct

* xlsclients lists clients, not windows, so gtk_window_set_wmclass has nothing

* Options --class and --name are only available for gnome programs (BTW, I see
	no reason not add support for these commandline options to GTK,
	though I didn't look at the code yet).

 I'm sorry for this.
