[Cocci] Adding a field to struct and new line issues

[Jerome Glisse <jglisse@redhat.com>]

Hi,

I am trying to add a field to struct however coccinelle insist on
adding it on the same line as struct name definition ie:

spatch:
@@
@@
struct foo {
+int roto;
...
}

original c code:
struct foo {
    int titi;
};

result:
struct foo {int roto;
    int titi;
};


This is kind of ugly and i am at loss trying to force a new line ie:
struct foo {
    int roto;
    int titi;
};



Funny thing, trying to out smart coccinelle with:
@@
identifier I1;
type T1;
@@
struct foo {
T1 I1;
+int roto;
...
}

Gives:
struct foo {
    int titi;int roto;
};


I am still scratching my head on how i can force a new line. There
does not seem to have \n or any escape sequence i can use to force
new line.

Thank you for any pointers toward that.
Jérôme
