Last change on this file since 0ec4eb0 was f5d9c37, checked in by Peter A. Buhr <pabuhr@…>, 2 years ago

harmonize separator manipulators names with newline names: change from sep, sepTuple, sepEnable, sepDisable, sepOn, sepOff to sepVal, sepTupleVal, sepOn, sepOff, sep, nosep; fix bug printing null string with WD so no separator
