Title: clear In[ ] prompt numbers again

this stopped worked in trunk recently, which makes for an annoyance when version controling notebooks, where clearing output used to also clear the In[] prompt numbers.

This is a simple fix, but I just wanted to ping @Carreau, since he was the last to make changes here, to make sure I haven't overlooked some case where this won't work.
