title: Automatically add svn:needs-lock
body: <p>Hi I was wondering if there is a way for the SVN server to automatically assign the svn:needs-lock property on any file that is binary and not textual. </p>
  
  <p>We have a rather small developers team but resting on everyone to remember to set this property on newly created binary files doesn't make sense since it's very easy to forget such a thing.</p>
