title: Merge a Branch into Trunk
body: <p>I'm facing a peculiar problem with SVN <code>merge</code>. I want to merge from a dev branch to trunk.
  We have multiple dev branches cut off the trunk at the same time.</p>
  
  <p>I'm merging one of those branches to trunk with this command:</p>
  
  <pre><code>svn merge trunk branch_1
  </code></pre>
  
  <p>I see changes that are not part of this branch, getting merged into trunk.
  What am I doing wrong ?</p>
  
  <p>SVN Version : </p>
  
  <blockquote>
    <p>Subversion command-line client, version
    1.6.16-SlikSvn-tag-1.6.16@1076804-WIN32.</p>
