title: Getting the full git log after rolling back to a previous version
body: <p>I'm new to git, and probably not using correct terminology, so bear with me :)</p>
  
  <p>Let's say I have a repository with 5 changes, e.g.</p>
  
  <pre><code>D:\test\gitrepo2&gt;git log --oneline
  3a5fd33 555
  3cfbfae 444
  e9a78c8 333
  a618586 222
  b80d5e1 111
  </code></pre>
  
  <p>I learned that I can sync back to an earlier revision by doing:</p>
  
  <pre><code>D:\test\gitrepo2&gt;git reset e9a78c8 --hard
  HEAD is now at e9a78c8 333
  </code></pre>
  
  <p><strong>My question is: after doing this, how can I get the full log, so that I can go back to the most recent revision?</strong></p>
  
  <p>Running log no longer shows those revisions:</p>
  
  <pre><code>D:\test\gitrepo2&gt;git log --oneline
  e9a78c8 333
  a618586 222
  b80d5e1 111
  </code></pre>
  
  <p>I also tried add the --all switch, which didn't make a difference. In Mercurial, under the same scenario, running 'hg log' gives the complete log even after I update to an earlier revision.</p>
