Greetings,

I was playing around with spatch in an attempt to create a wrapper 
utility for renaming.

Given the following script:
@ rn_dec @
type T;
identifier I = i;
@@

- T I
+ T b
;

And the following input:
void f() {
     int i;
     for (int i;;) { ; }
}

The following patch is generated:
diff =
--- main.c
+++ /tmp/cocci-output-9754-fec11b-main.c
@@ -1,4 +1,4 @@
  void f() {
-    int i;
+    int b;
      for (int i;;) { ; }
  }

However, I would expect the declaration inside the 'for' to be replaced too.
My only questions is: is the observed behaviour intended?

Cheers!
