title: specs2 run a specific test
body: <p>I'm trying to run a specific test with <code>specs2</code> and I'm running into one minor issue there. This is the code I'm running: </p>
  
  <pre><code>import org.specs2._
  
  class DemoSpec2 extends Specification {
    def is = s2"""
  
    This is a specification to check the 'Hello world' string
  
    The 'Hello world' string should
      contain 11 characters              ${Set11().e1}        ${tag("feature")}
      start with 'Hello'                 ${Set2().e2}         ${tag("abc")}
  
                                         """
  
    case class Set11(){ def e1 = 1 must_== 1 }
    case class Set2(){ def e2 = 1 must_== 1 }
  
  }
  </code></pre>
  
  <p>The <code>${tag("feature")}</code> part makes an extra line in the output. So it looks like: </p>
  
  <pre><code>[info]   The 'Hello world' string should
  [info]     + contain 11 characters
  [info]         
  [info]     + start with 'Hello'
  </code></pre>
  
  <p>I don't want the extra line. What I'm doing wrong?</p>
