This patch adds a BUFFER argument to format-mode-line, and should
make it possible to avoid calling set-window-buffer in that loop.

However, I still think we should find out why redisplay
happens inside that loop, since in all appearance, there should
be no redisplay.

Revision 1.67 of lisp/buff-menu.el changed list-buffers-noselect so that
it now does

        (set-window-buffer (selected-window) buffer)

once for every buffer while building the buffer menu.  On my Windows XP
machine, this makes Emacs briefely display every buffer for a fraction
of a section before displaying the buffer menu.  Very annoying!

This patch fixes it without (apparently) causing a loss of
functionality:
