ksebasti found several issues with this widget:
printf ("%n%4d", 0) prints 0x04 0x00 0x00 0x00 0x00
printf ("%n%n%n") prints junk
printf ("%n") prints junk
If we keep %n around at all, it needs to compose sensibly.
We could make it mean "total record length", so that the
previous three cases would print
printf ("%n%4d", 0) would print 0x05 0x00 0x00 0x00 0x00
printf ("%n%n%n") would print 0x03 0x03 0x03
printf ("%n") would print 0x01

Table-1 in langreg.pdf needs to be corrected to indicate the absence of %n
printf specifier.
