As it turns out, whoever wrote that wasn't paying close enough
attention, as the third argument is supposed to be for events (to
satisfy commands that ask for "e", "k", "K", or "U").

It seems that `call-interactively' propagates the prefix argument to the
called function automatically (it did with a test command that printed
its arg in my git emacs -Q), so you should be able to remove the last 2
arguments to each call and it should Just Work(tm).

I have a patch, attached, that does just that.
