[cocci] GNU-style function calls

Hi!

I work on GCC, meaning we use GNU-style function calls, where the
call operator is preceded by a whitespace, like so:

  foo (a, b);

I've had decent luck with applying Cocci to the codebase, but if Cocci
rewrites a call, it removes the whitespace preceding the call operator:

  /tmp$ cat test.cc
  void
  thing ()
  {
    foo (a, b);
  }
  /tmp$ cat test.cocci
  @@
  expression x, y;
  @@

  - foo (x, y);
  + foo (y, x);
  /tmp$ spatch --sp-file test.cocci --c++=3D14 test.cc
  init_defs_builtins: /usr/lib64/coccinelle/standard.h
  HANDLING: test.cc
  diff =3D=20
  --- test.cc
  +++ /tmp/cocci-output-157607-636042-test.cc
  @@ -1,5 +1,5 @@
   void
   thing ()
   {
  -  foo (a, b);
  +  foo(b, a);
   }
  /tmp$=20

This isn't too much of a problem; I go back and modify the function
calls manually, but it would be nice if Cocci handled it.

Is it possible to keep the spaces in line with the code style w/ Cocci?

Thanks in advance!  Have a lovely day.
