The problem is that there aren't distinct functions in Emacs to (1)
interpret the mode-line-format variable and (2) display it.  In xdisp.c,
display_mode_element is used for both purposes, and it doesn't have a
Lisp binding.

Since I saw your request, I've been hacking on my own Lisp version, which
I'll post either there or gnu.emacs.sources shortly...
