title: How to move to the last point position before popping mark-ring?
body: <p>I often come to below scenario: </p>
  
  <p>Assumptions:
  I have 5 marks in total:  current mark is at position <code>5</code>, and 4 marks on mark-ring at positions: <code>4</code>,<code>3</code>,<code>2</code>,<code>1</code> respectively. My point location is somewhere far away, say, <code>100</code>.</p>
  
  <p>Situation:
  Now I found an error at <code>4</code>, so I <kbd>C-u C-SPC</kbd> to jump to position <code>4</code> and fixed it. But I forget to save the previous point position <code>100</code>. How do I jump back?</p>
  
  <p>I understand that one good practice is to save the point position before jump. But similar jumps happens very frequently and in times the problem happens 1 or 2 times. Once it happens, it will be nice if there could be a remedy to it, since it seems a special position too, (last point position before popping mark-ring).</p>
  
  <p>Without a remedy, it seems a painful trip to manually go from position <code>4</code> to <code>100</code> manually, even it happens in a low frequency.</p>
