From 032306f2fabf94e09615ab96e52591cdf04f29a3 Mon Sep 17 00:00:00 2001
From: jlam <jlam@pkgsrc.org>
Date: Thu, 12 Jul 2007 18:32:49 +0000
Subject: Update sysutils/install-sh to 20070712.  Changes from previous
 version include:

* Drop support for "-b=..." and "-t=..." which are transformation options
  that are not supported by BSD install.

* Add support for "-b" and "-B fmt" to allow backing up existing files.
  Only specifying "-b" yields a backup suffix of ".old" and "-B fmt"
  allows for sprintf(3)-style backup suffices.  Number backups are
  supported using awk(1).
