title: Ant: don't print build.xml indentation with echo or fail
body: <p>Say I have the following in my <code>build.xml</code> file:</p>
  
  <pre><code>&lt;target name="FOO"&gt;
      &lt;echo&gt;a
            b
            c
            d&lt;/echo&gt;
  &lt;/target&gt;
  </code></pre>
  
  <p>The result is:</p>
  
  <pre><code> [echo] a
   [echo]               b
   [echo]               c
   [echo]               d
  </code></pre>
  
  <p>I want the output to be:</p>
  
  <pre><code> [echo] a
   [echo] b
   [echo] c
   [echo] d
  </code></pre>
  
  <p>To get that, I could change <code>build.xml</code> to:</p>
  
  <pre><code>&lt;target name="FOO"&gt;
      &lt;echo&gt;a
  b
  c
  d&lt;/echo&gt;
  &lt;/target&gt;
  </code></pre>
  
  <p>But is there anything <strong>else</strong> I can do to get the same output?  Anything that keeps the <code>build.xml</code> indentation the same as the original, that is.</p>
