title: How to find commit when line was deleted/removed?
body: <p>I have a deleted line in a file in my Git repository. I knew some of the missing text, and the file that it was in, so I used <code>git log -S'missingtext' /path/to/file</code>.</p>
  <p>However, the only thing that came back was the commit in which I added the line containing the missing text. The text wasn't present in HEAD, and the commit that added it was present in my branch, so I knew that one of the commits in my branch's history must have removed it, but it wasn't showing up.</p>
  <p>After some manual searching, it turned out that the line was removed accidentally while resolving a conflict for a merge. So I'm wondering:</p>
  <ol>
  <li>Is this the reason why pickaxe couldn't find the commit that deleted the line?</li>
  <li>How could I have found where &quot;missingtext&quot; was deleted without digging through the history manually?</li>
  </ol>
  <p>Any insight on #1 would be great (I assumed that <code>git log -S</code> would give me my answer), but my real question is #2 since I'd like to be able to avoid this in the future.</p>
