Yes padding can be accomplished with map (requires
sligthly more typing).

The reason I propose it, is that I think this a more
useful behavier of zip, rather than the current behavier
where it only pads the first element.

I have interest in #zip's behavier, if there is oddities
then I ask why.. With 1.9 #zip has been extended, this
proposal is about fixing the behavier of that extension.
