title: Writing a pre-commit hook using SharpSvn. Does it lack svnlook propget?
body: <p>I am rewriting an older subversion precommit hook. In our company, we need to make sure that binary files are allowed on commit only if they have the property svn:needs-lock set before commit.</p>
  
  <p>I started writing the hook and it looks like every part of the hook works, but I cannot find how to read, if the property is set.</p>
  
  <p>I would assume, that SvnLookClient would have the SvnLookClient.GetProperty method, but the only one, that I see is SvnLookClient.GetRevisionProperty. Unfortunately GetRevisionProperty doesn't allow to pass the file in question. What am I missing here?</p>
  
  <p>After all, svnlook propget does allow to pass a repository, a transaction, a propertyname AND the path in the repository.</p>
