format-mode-line screws up list buffers

[Nick Roberts]

Evaluating (format-mode-line mode-line-process nil nil (current-buffer))
in the shell buffer used to give things like ":run".

Now it gives ":%srun".

This means that list-buffers has entries like:

. * *shell*                 22  Shell:%srun       ~/

This is due to changes in get_next_display_element since October 5th
(xdisp.c, version 1.913). Probably:

        * xdisp.c (get_next_display_element):
        If unibyte_display_via_language_environment is zero, display 8-bit
        chars in octal in unibyte buffer.
