According to the December 1988 draft, `*' as a scanf flag (between
a `%' and a conversion character) is an assignment suppression flag.
However, `%n' does not count as an assignment, nor is it a regular
conversion character (since no input is converted).  This leaves
me with the question:

  Does `%*n' write to anything, or is the `assignment' suppressed?

Note that `%*n' is completely useless if it is suppressed, since it
affects neither the stream nor any object.
