[patch ipp] Time Optimization

[Denis Barbier <nospam@thanx>]

Hi Ralf and others,

to speed up wml, i decided to store files inside a ``format'' file, as
TeX does. I create a file
   ## file includes.wml
   use wml::std::all
   use wml::des::all
   ##EOF##

process it through wml_p1_ipp:
   prompt> wml_p1_ipp -S /usr/lib/wml/include includes.wml > includes.pass1

and include this file via
   #include "includes.pass1"

This file may be read verbatim, wml_p1_ipp should do nothing on it. So i
added these few lines to ipp.src and now
   #include "includes.pass1" verbatim
read ``includes.pass1'' without invoking ipp on it.

I admit that speed-up time is not terrific.

Denis
