title: sed: unescaped newline inside substitute pattern?
body: <p>This code: </p>
  
  <pre><code>echo Foo | sed -e 's/Foo/Bar'
  </code></pre>
  
  <p>results in <code>unescaped newline inside substitute pattern</code> (instead of the expected <code>Bar</code>).</p>
  
  <p>I'm obviously overlooking something simple, bash/sed/escaping related, but I can't find out what's causing this?</p>
