subversion/libsvn_ra_svn/protocol says:

  stat
    params:   ( path:string [ rev:number ] )
    response: ( ? entry:dirent )
    dirent:   ( name:string kind:node-kind size:number has-props:bool
                created-rev:number [ created-date:string ]
                [ last-author:string ] )
    New in svn 1.2.  If path is non-existent, an empty response is returned.

... but the "name:string" parameter is not present:

>>> ( stat ( 4:/foo ( ) ) )
<<< ( success ( ( ) 0: ) )
<<< ( success ( ( ( file 0 false 1 ( 27:2007-06-01T19:22:53.890625Z ) ( 6:Daniel ) ) ) ) )
