Actually, it originates from ksh, where our (Posix') $ENV usage
originates, too.

The most important part now though is (sorry for shouting :):

	IT IS HIGHLY RECOMMENDED THAT YOU START YOUR SHELL SCRIPTS
	WITH

		#!/bin/sh -p

	NOW!

This is in particular true for things that can be invoked by random
users like login shell scripts, but might also come handy for things
like /dev/MAKEDEV.

For the reasoning why this is useful, refer to PR docs/1383.  (This PR
can now be closed after updating the ppp man page.)

Never trust an operating system you don't have sources for. ;-)
