Summary: Inappropriate number of values should be defined sensibly

Report section 9.17, s.v. "values", says that passing an inappropriate
number of values to a continuation is undefined.  I believe it ought to
be defined thus:

	If an expression supplies too many values to its continuation,
	the excess values are discarded.  If it supplies too few values,
	the deficient values are set to the unspecified value.

In particular, this paves the way to eliminating "the unspecified value"
in favor of simply returning zero values.

Promises become binding when there is a meeting of the minds and consideration
is exchanged. So it was at King's Bench in common law England; so it was
under the common law in the American colonies; so it was through more than
two centuries of jurisprudence in this country; and so it is today.
