Please stop asking the same question over and over.  In the context of a
macro definition, <+... f(...) ...+> will only match what is from the same
logical source line.  Because that is all that there is in a macro
definition.  If Coccinelle is working on a macro definition, it works only
on that macro definition.  If it is working on a function definition, it
works only on that function definition.
