Well we had kept it so that if need be in the future they ask us to show
children in the clipboard-view, we can just set "add_children" paramter to
true. But since we don't need it, its nice to get rid of that code.

Hmm didn't know that.

I agree. No point in keeping that extra structure (if it doesn't keep any
additional info besides what Gtk+ does for us).

/me holds up green flag.
