title: Git, push working directory without committing
body: <p>Sometimes I'll be working on code on a desktop then find I have to go*, before I've finished implementing a full feature. Then later ill be on another computer, and want to carry on where I left off. Is it possible to push the working directory (so without committing) to a remote repo (such as on GitHub)?</p>
  
  <p>* I ran this will happen suddenly, so I need to go quickly and not have to think about writing a commit message. </p>
