git push 说一切都是最新的，但肯定不是

Question

我有一个公共(public)存储库。没有其他人对它进行 fork 、 pull 或做任何其他事情。我对一个文件做了一些小改动，成功提交，并尝试推送。它说“一切都是最新的”。没有分支机构。我对 git 非常非常陌生，我不明白到底发生了什么。

git remote show origin 告诉我:

HEAD branch: master
  Remote branch:
    master tracked
  Local ref configured for 'git push':
    master pushes to master (up to date)

有什么想法可以让我明白它不是最新的吗？

谢谢

更新: 混帐状态:

# On branch master
# Untracked files:
#   (use "git add ..." to include in what will be committed)
#
#       histmarkup.el
#       vendor/yasnippet-0.6.1c/snippets/
no changes added to commit (use "git add" and/or "git commit -a")

git branch -a:

* master
  remotes/origin/master

git fsck:

dangling tree 105cb101ca1a4d2cbe1b5c73eb4a238e22cb4998
dangling tree 85bd0461f0fcb1618d46c8a80d3a4a7932de34bb

更新 2:我重新打开修改后的文件，我知道我所做的修改消失了。所以我再次添加了它们，完成了 git status、git add filename、git commit -m "(message)" 的繁琐操作，以及git push origin master，突然间它按照预期的方式工作。

更新 3:git reflog 输出:

尝试

git config push.default tracking

http://git-scm.com/docs/git-config :

推送默认值

定义 git push 在命令行上没有给出 refspec 时应该采取的操作，远程中没有配置 refspec，并且命令行上给出的任何选项都没有暗示 refspec。可能的值是:

* nothing - do not push anything.
* matching - push all matching branches. All branches having the same name in both ends are considered to be matching. This is the default.
* upstream - push the current branch to its upstream branch.
* tracking - deprecated synonym for upstream.
* current - push the current branch to a branch of the same name.
