title: how to git log with date-time and file names in one line
body: <p>I would like to have an git log (or in any other way) output like this, </p>
  
  <pre><code>2015-01-14 10:33:14 main.cpp
  2014-10-30 11:30:22 some.cpp
  2014-10-27 10:15:43 another.cpp
  2014-10-27 09:41:22 main.cpp
  2014-10-24 19:15:08 some.cpp
  </code></pre>
  
  <p>Basically the output should contain date, time and the file changed. And one entry should be in one line as example shows. 
  I have checked pretty formats, but could not find a way to output the file names.</p>
  
  <p>So, how to get something like this from git commands?</p>
