title: Find when a file was deleted in Git
body: <p>I have a Git repository with n commits.</p>
  
  <p>I have a file that I need, and that used to be in the repository, and that I suddenly look for and think "Oh! Where'd that file go?"</p>
  
  <p>Is there a (series of) Git command(s) that will tell me that "file really_needed.txt was deleted at commit n-13"?</p>
  
  <p>In other words, without looking at every individual commit, and knowing that my Git repo has every change of every file, can I quickly find the last commit that HAS that file, so I can get it back?</p>
