The attached patch is a proof of concept for an extension of
doc2texi.el.  AFAICS it works.  It calls the preprocessor from within
doc2texi.el.  This could be done somewhat more portable than just
calling "cpp -DTERM_HELP", though.  But I don't know an easy way to
get the values of $(CPP) and $(CPPFLAGS) into the elisp processor
other than through the enviroment (which seems to be quite easy, but
not quite elegant).  How portable should this step be?  Will
gnuplot.info be prebuilt in releases?
