title: How to do a multiline commit message in git?
body: <p>I have been doing a oneline commit message for some time now but it doesn't give the entire information on the commit.</p>
  
  <pre><code>git commit -m "message"
  </code></pre>
  
  <p>I once used git Gui tool and it had option to do multiline commit message. One in header and one in detail.
  How do we do it from the command line?</p>
  
  <p>And can some one explain any good practice to commit bug fix and new changes? I normally write "NEW:" or "FIX" at start of the commit message, i would like to know how you guys do this?</p>
