title: Git / Github - problem with commit visibility / history / git log -S
body: <p>I have a pretty weird problem with git. <br />
  When I use the command: <br />
  <code>git show {number of commit}</code> <br />
  It shows me a commit that I made, and in this commit, I can clearly see that I used the &quot;boolToString&quot; function. With applies that the commit is existing. But when I use <br />
  <code>git log -S boolToString {path to file}</code><br />
  it does not find commit with this change. The path to file is correct because if I type some phrase that was there before my commit it is returning results. Does any of you come with a problem similar to mine? I would be more than thankful for any hints or ideas about what's going on.</p>
