Subject: [Bug] git diff assumes executable permissions change is always 0755
To:     git@vger.kernel.org
Content-Type: text/plain; charset="UTF-8"
Sender: git-owner@vger.kernel.org
Precedence: bulk
List-ID: <git.vger.kernel.org>
X-Mailing-List: git@vger.kernel.org

git 2.24.0
macOS 10.14.6

To reproduce:
 - Start a file, commit in git
 - chmod 0744 file.txt
 - git diff
 - ls -l file.txt

git diff reports :
old mode 100644
new mode 100755

expected:
git lists actual permissions of file
new mode 100744
File's permissions are 0744 (-rwxr--r--)

Thanks,
