From a8dacf6f0c85b10ae9582a003ed02b9b02bbc3cb Mon Sep 17 00:00:00 2001
From: Ingo Schwarze <schwarze@cvs.openbsd.org>
Date: Sun, 15 Jan 2012 11:43:46 +0000
Subject: Document the EXIT STATUS and remove an outdated related comment.

While here,
* as usual, the "first appeared" clause requires fixing, and
* mention the date of the original implementation,
using information from the CSRG archive CD 1.

Triggered by a question asked by lum@, feedback and ok jmc@.
