NEMO and ZENO filestructure not 100% same

[teuben]

Both NEMO and ZENO filestructure have made minor modifictions since the 1986 version. There is one important deficiency in NEMO which has not been fixed: multiple same named item are not correctly handled in NEMO. Also some integers that are stored in octal are not transferred properly in a tsf | rsf | tsf pipe test. There may be more.
