问题：
Occasionally I dropped a DVD-rip into a website project, then carelessly git commit -a -m ... , and, zap, the repo was bloated by 2.2 gigs. 有时，我将DVD-rip放入一个网站项目中，然后不小心git commit -a -m ... ，然后，zap的回购膨胀了2.2个演出。 Next time I made some edits, deleted the video file, and committed everything, but the compressed file is still there in the repository, in history. 下次我进行一些编辑，删除视频文件并提交所有内容，但是压缩文件仍在历史记录中。
I know I can start branches from those commits and rebase one branch onto another. 我知道我可以从这些提交开始分支，并将一个分支重新建立到另一个分支。 But what should I do to merge together the 2 commits so that the big file didn't show in the history and were cleaned in garbage collection procedure? 但是，我应该怎么做才能将2个提交合并在一起，以便大文件不显示在历史记录中，并在垃圾回收过程中清除？
