Comment 2 for bug 117450

I just changed (following Gustavo's idea) this:

def close(self, quitting=False):
- close = self.document_save_hook(can_cancel=(not quitting))
+ close = self.document_save_hook(can_cancel=True)

Nothing else was changed. It's not beautiful but I don't know if I don't see if can_cancel argument may have an interest.
