Is there a %i?  I don't have the proposed Standard at hand but I don't
recall a %i format.  I'll look this up and if nobody else responds by
the time I find out, I'll let you know what %i is supposed to do.

Unsigned int is (now) required to be passed in exactly the same format
as plain int, so it doesn't matter from the viewpoint of implementing
printf().  It does matter from the viewpoint of the USER of printf(),
and this has been fixed in the latest edition of the proposed Standard.
