         on network drives).

         This 'feature'is now removed as it penalizes every correct
         path passed, and also breaks behavior of e.g.
           'svn status .' returns '!' file, because there is only a "File"
             on disk.
            But when you then call 'svn status file', you get '? File'.

         As JavaHL is designed to be platform independent I assume users
         don't want this broken behavior on non round-trippable paths, nor
         the performance penalty.
