当我在OS X上克隆
Linux源代码时,它们会立即被更改,并且git reset –hard不会将内容恢复.这是一个完整的会议：
$git clone git://github.com/torvalds/linux.git
$cd linux
$git status
On branch master
Your branch is up-to-date with 'origin/master'.
Changes not staged for commit:
(use "git add ..." to update what will be committed)
(use "git checkout -- ..." to discard changes in working directory)

我们可以看到,克隆后文件立即发生了变化.甚至不是他们的元数据,而是内容：
git diff include/uapi/linux/netfilter_ipv6/ip6t_HL.h

到底是怎么回事？为什么在克隆后立即修改文件？
