[cocci] Bug with '*' to display a match on the subsequent rule.

[Eric Wheeler <cocci@lists.ewheeler.net>]

Hello,

I may have found a bug:

	@ r1 @
	type T;
	identifier I;
	@@
	*T I;

	@ r2 @
	@@
	f()
	{
	}
	+void a(){}

which prints this error:

	init_defs_builtins: /usr/local/coccinelle-git/bin/lib/coccinelle/standard.h
	File "cocci/broken.cocci", line 12, column 0, charpos = 57
	  around = '+',
	  whole content = +void a(){}

but if I remove the '*' or turn it to a '-' then it works:

	@ r1 @
	type T;
	identifier I;
	@@
	-T I;

	@ r2 @
	@@
	f()
	{
	}
	+void a(){}

with the diff:

	--- t.c
	+++ /tmp/cocci-output-6974-08cd95-t.c
	@@ -5,11 +5,13 @@ typedef struct
		int w;
	 } A;
	 
	-A a, b;
	-
	 #define NOMATCH(s1, s2, member) printf(#s1  "." #member "!=" #s2 "." #member);
	 f()
	 {
	 }
	 
	+void a()
	+{
	+}
	+
	 // functions here


Here is the t.c file:

	typedef struct 
	{
		int x, y, z;
		int u, v;
		int w;
	} A;

	A a, b;

	#define NOMATCH(s1, s2, member) printf(#s1  "." #member "!=" #s2 "." #member);
	f()
	{
	}

	// functions here
