问题[msys](unix)

我启动了一个 git-bash 窗口，然后输入以下命令：

git-bash ~$ echo $BASH_VERSION
4.4.23(1)-release
git-bash ~$ type cd
cd is a shell builtin
git-bash ~$ cd tmp
git-bash ~/tmp$
# Change of directory is NOT refelected on git-bash window title

git-bash ~/tmp$ ssh user@linux
[user@linux ~]$ echo $BASH_VERSION
4.4.20(1)-release
[user@linux ~]$ type cd
cd is a shell builtin
[user@linux ~]$ cd tmp
[user@linux ~/tmp]$
# Change of directory   IS   refelected on git-bash window title

为什么 git-bash 不更新自己的窗口标题而远程 bash 更新？
