For those who argue "who would ever use it?", I would :-) 
Note that this does not support and is independent of supporting
arbitrary bases. I don't think we need to support arbitrary bases, but
if we did I would vote for ".precision" to mean ".base" for "%d"... ie;
"%3.3d" % 5 == " 12"
I think supporting arbitrary bases for floats is way overkill and not
worth considering.
