Fixed.

Note that the arg list to format-mode-line has been reworked.
Here is the new doc string:

+--------------------
| format-mode-line is a built-in function in `C source code'.
| (format-mode-line format &optional face window buffer)
|  
| Format a string out of a mode line format specification.
| First arg format specifies the mode line format (see `mode-line-format'
| for details) to use.
|  
| Optional second arg face specifies the face property to put
| on all characters for which no face is specified.
| t means whatever face the window's mode line currently uses
| (either `mode-line' or `mode-line-inactive', depending).
| nil means the default is no face property.
| If face is an integer, the value string has no text properties.
|  
| Optional third and fourth args window and buffer specify the window
| and buffer to use as the context for the formatting (defaults
| are the selected window and the window's buffer).
