  message:
    Fix permanancy of BUFFER-LIST arg to list-buffers-noselect (Bug#7749).

    * buff-menu.el (Buffer-menu-buffer-list): New var.
    (Buffer-menu-revert-function, list-buffers-noselect): Use it, so a
    restricted buffer list is not lost on revert (Bug#7749).

committed more than just buff-menu.el as advertised in the log
message.
