         the passed path. (An extremely expensive operation; especially
         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.
