Description
By adding a 'limit' parameter, clients can in the best case quickly locate the "path-appeared-revision" (what revision did this object first show up at this path in?) in a far more efficient manner (using closest-copy) than the current method of calling svn_ra_get_logs() with a limit of 1 (which has to crawl the history of the object from peg revision to its origin), and in the worst case match the current method's performance.
