Thanks for your work so far.

I tested your patch quickly.  It works!

But I noticed that C-x 5 u without prefix arg errors.  This is probably
not intended.  I think you rather want to test the raw prefix arg with
`consp', not with `listp'.  But why not just use (interactive "p")?

Regards,

Michael.
