If a command or interface first appeared in PWB/UNIX, UNIX System III or

UNIX System V mention it.  Only do so in manual pages with a

Prompted by the comparison of System V and BSD commands and interfaces
in Sun's "System V Enhancements Overview" document.

checked against manuals on bitsavers, TUHS archive and CSRG archive CDs
