	* src/number-match.c: Currently, two-digit years are converted to
	four-digit years (ccyy) by assuming that cc is the same as in the
	current wall date.  The problem with that is that on 1999-12-31,
	entering any future dates in two-digit-year form will be
	misinterpreted; while on 2000-01-01, any past dates entered in
	two-digit form will be misinterpreted.  (I use the term
	"misinterpreted" with the assumption that one is much more likely
	to intend a date a few days away than 99 years away.)
