*	sum-each, mul-each: handle no vars case.	Kaz Kylheku	2022-01-11	1	-0/+42
	* stdlib/arith-each.tl (sys:arith-each): If there are no vars, then just reduce to the identity element value. This is alreading happening fine for the each-prod family of operators. * tests/016/arith.tl: Test cases covering the no vars and empty iteration identity element cases for sum-each and mul-each, as well as the -prod variants. txr.1: Document empty iteration and empty vars behavior for arithmetic each operators as well as the each-prod family.
