iostream.hfa @ 0aa77e6

Last change on this file since 0aa77e6 was f5d9c37, checked in by Peter A. Buhr <pabuhr@…>, 16 months 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
Property mode set to `100644`
