git - 新克隆的 git 存储库显示有本地更改

Question

我不太明白，为什么新克隆的 git 存储库显示有更改未提交提交。

这是一个简短的例子:

    [dpetrov@macbook-pro ~/work]$ git clone /tmp/git/pollers.git pollers
    Cloning into 'pollers'...
    done.
    [dpetrov@macbook-pro ~/work]$ cd pollers/
    [dpetrov@macbook-pro ~/work/pollers (master)]$ git status
    On branch master
    Your branch is up-to-date with 'origin/master'.

    nothing to commit, working tree clean
    [dpetrov@macbook-pro ~/work/pollers (master)]$ git checkout pollers-1.0
    gBranch pollers-1.0 set up to track remote branch pollers-1.0 from origin.
    Switched to a new branch 'pollers-1.0'
    i
    [dpetrov@macbook-pro ~/work/pollers (pollers-1.0)]$ git status
    On branch pollers-1.0
    Your branch is up-to-date with 'origin/pollers-1.0'.

    Changes not staged for commit:
      (use "git add <file>..." to update what will be committed)
      (use "git checkout -- <file>..." to discard changes in working directory)

        modified:   share/mibs/IANAifType-MIB.mib

    no changes added to commit (use "git add" and/or "git commit -a")
    [dpetrov@macbook-pro ~/work/pollers (pollers-1.0)]$ git diff share/mibs/IANAifType-MIB.mib
    diff --git a/share/mibs/IANAifType-MIB.mib b/share/mibs/IANAifType-MIB.mib

任何线索如何调试以及可能导致它的原因是什么？

非常感谢。

这是文件名中区分大小写的问题:两个不同的文件存储在 git 中，它们的名称只有大小写不同。
检查差异时，git 会收到两个名称之一的“错误”内容。
