I think code like this:

int foo (void)
{
  return (struct bar) { .f1 = 10,
			 .f2 = 20,
			 };
}

should be indented better.  Maybe so:

  return (struct bar) { .f1 = 10,
			.f2 = 20,
		      };

There are also strange interactions with declarations, eg. adding a
a declaration before the return changes the indentation to:

int foo (void)
{
  int i = 1;
  return (struct bar) { .f1 = 10,
      .f2 = 20,
      };
}
