From 9f3628bd459f371f0c2fda05e29e8149d01e1c91 Mon Sep 17 00:00:00 2001
From: Jim Meyering <jim@meyering.net>
Date: Fri, 2 Jul 2004 17:00:53 +0000
Subject: Add short names -t and -T for --target-directory and
 --no-target-directory options, respectively.

(NO_TARGET_DIRECTORY_OPTION, TARGET_DIRECTORY_OPTION):
Remove.  All uses changed to 'T' and 't', respectively.

(long_options, main, usage): Add -t and -T as
aliases for --target-directory and --no-target-directory,
respectively.
