title: If pattern matched delete newline character in that line
body: <p>Let say pattern is string "Love"</p>
  
  <p>input</p>
  
  <pre><code>This is some text
  Love this or that
  He is running like a rabbit
  </code></pre>
  
  <p>output</p>
  
  <pre><code>This is some text
  Love this or thatHe is running like a rabbit
  </code></pre>
  
  <p>I've noticed that sed is very unpleasant for deleting newline characters, any idea?</p>
