title: Scala: How to print all values in a long vector without ellipsis
body: <p>I'd like to print all values of a vector which has about 700 elements. By default, a relatively small number (maybe 100 or so) are printed, and then an ellipsis (...). Is there a way to print all the values?</p>
  
  <p>Of course, I could go through the elements one by one, but I'm hoping to avoid that.</p>
  
  <p>EDIT: I am printing stuff via println. Unless I've misunderstood something, changing maxPrintString doesn't seem to affect println output (or toString, since I suppose println must be calling toString). </p>
