Nothing is exceptionally wrong with it, except it's not
as flexible. Since everything is show'n, how would you
handle things like "%5.2f" or "%*d"? In Brian Huffman's
version it's almost trivial to add. I know I can use 
formatDouble and whatnot, but the code looks cluttered
this way. "C" printf has many pitfalls, but I like its
terseness.
