title: Regex to combine multiple rows?
body: <p>Is it possible to use a regex to combine multiple textrows?
  For example row 1 with row 2, row 3 with row 4, etc, etc...
  If I have rows like those:</p>
  
  <pre><code>s89j3hjd34nsd
  j8324jdsfjfs
  8hasdk3491es
  hdf63hadsi9
  </code></pre>
  
  <p>Can I remove (replace with nothing) the ending of the row ($) for every two lines.
  So it will result would be:</p>
  
  <pre><code>s89j3hjd34nsdj8324jdsfjfs
  8hasdk3491eshdf63hadsi9
  </code></pre>
