title: undo dropped commit in sublime merge
body: <p>I just switched to sublime merge away from github desktop (what an improvement), however I just performed the menu option <code>Edit commit\drop selected commits</code> thinking it was the equivalent of the <code>undo commit</code> button in github desktop.</p>
  
  <p>That has not undone the commit I had selected (which was the most recent in the tree) as I thought, it has dropped (erased) it completely. </p>
  
  <p>I know there are many posts discussing the <code>reflog</code> and of course I'll study that but would love a direct (command line if necessary) solution which fixes this exact problem first, then I can learn more later.</p>
