    fromcwd.cc: Truncate search at the first extension in preference order
    
    * fromcwd.cc (FindVisitor): Truncate search at the first extension
      found in preference order in the same directory so that no multiple
      setup files for the same (sub-)mirror are processed by do_local_ini.
