title: SVN Mergeinfo properties on paths other than the working copy root
body: <p>I have an SVN repository where I have trunk and a branch.</p>
  
  <p>I intend to merge the trunk into the branch at regular intervals, however, when I do this I see many property status changes, in addition to actual file content changes.</p>
  
  <p>On further investigation the property changes are mergeinfo properties. I wouldn't expect this because we <em>always</em> branch and merge from the top root level.</p>
  
  <p>I used the <code>svn propdel</code> command and removed all mergeinfo properties from the branch WC (then reverted the change on the root) before merging trunk in, and the problem went away.</p>
  
  <p>So the question is, how did my branch get all these mergeinfo changes in it at sub-directory levels?</p>
