How can I start urxvt as fullscreen ?

[Wang Lei <wanglei 198112 gmail com>]

Hi, all!

I like only 1 window on screen. I use match window to make emacs, xpdf
and Iceweasel start as fullscreen. But how can I do to urxvt ? It has
border all the time.

I tried to add the code like this into .sawfish script, but it makes
the wm dead.

-------code---------
(system "urxvt &")
(while (not (get-window-by-name-re "lei debian") )
    t)
(maximize-window-fullscreen-toggle (get-window-by-name-re "lei debian"))
-------code---------

Could anybody help?
