title: Pushing only one folder to remote repo
body: <p>I'm using Git 1.7.4.1.  I want to push commits I did on one folder to my remote repo.  How do I push only changes from one folder to my remote repo?  All the documentation I've found only lists how to push the entire repo ...</p>
  
  <pre><code>davea-mbp2:systems davea$ git push origin trunk
  Password: 
  To http://dalvarado@mydomain.com/systems.git
   ! [rejected]        trunk -&gt; trunk (non-fast-forward)
  error: failed to push some refs to 'http://dalvarado@mydomain.com/systems.git'
  To prevent you from losing history, non-fast-forward updates were rejected
  Merge the remote changes (e.g. 'git pull') before pushing again.  See the
  'Note about fast-forwards' section of 'git push --help' for details.
  </code></pre>
  
  <p>The conflicts I'm being warned about do not apply to the folder that I want to push.  Any help is appreciated, - Dave</p>
