Sigh, another correction for the record: it was _three_ times!!! Early
versions of IPv4 (IEN-28, confusingly titled "Draft Internetwork Protocol
Specification: Version 2" - it was actually somewhere between 3.1 and 4;
then IEN-41) also had them; they were removed shortly thereafter (IEN-44).

(Excuse me if I'm having a hard time keep track of this; they got put in
and taken out so many times my head is spinning... :-)
