title: Join all lines with tabs inserted (vim)
body: <p>I have a tab delimited file (one line). I can easily enough replace the tabs with new lines so that I can see what fields are in what position</p>
  
  <pre><code>:%s/\t/\r/g
  </code></pre>
  
  <p>How can I do the inverse, after I've edited the fields? I could record a macro:</p>
  
  <pre><code>Js&lt;tab&gt;Esc
  </code></pre>
  
  <p>And then repeat it all the way down - but is there an easier way?</p>
