Why bother?  This would be very complicated and lead to many mistakes due
to an unclear definition of whitespace or whatever.
I have a file called "beginc", it's a shellscript, and it creates a file
which begins something like this:

		#include <stdio.h>
		#include "/u/flaps/ajr.h"
		#include <strings.h>
		#define TRUE 1
		#define FALSE 0

		main(argc,argv)
		int argc;
		char *argv[];
		{

and then puts you in $EDITOR on the file.  This approach is much better
than any #exclude op.  It's more easily disabled or modified because you
don't have the reverse situation of deleting things by adding in lines.
