redraw-modeline is an alias for `force-mode-line-update' in `subr'.
(redraw-modeline &optional all)

Force redisplay of the current buffer's mode line and header line.
With optional non-nil all, force redisplay of all mode lines and
header lines.  This function also forces recomputation of the
menu bar menus and the frame title.
