I think that change is likely to break things.  If you WANT a hex
string, you probably want it to be all hex, regardless of value.

I would expect that each use of %x probably has a certain number of bits
in mind.  Perhaps %x should take a number of bits and output modularly.
So %24x would output 24 bits' worth.  Always unsigned.
