From 43d6a146780d20450b3264783f6ddfba83217282 Mon Sep 17 00:00:00 2001
From: tjr <tjr@FreeBSD.org>
Date: Thu, 25 Jul 2002 10:57:39 +0000
Subject: Add a -P/-o physical option which behaves similarly to bash/ksh's
 options by the same name. This option makes the cd and pwd builtins behave
 physically (as opposed to logically) by default.
