The spec says:

ArgClose
    X     // variadic T t,...) style
    Y     // variadic T t...) style
    Z     // not variadic

But in reality:
------------------------------------
void ff(int x, ...) {}
void gg(int[] x ...) {}
void main() {
   assert( (&ff).mangleof == "PFiYv" );  // passes
   assert( (&gg).mangleof == "PFAiXv" ); // passes
}
------------------------------------

This shows X and Y are swapped. The fixed rule should be:

ArgClose
    X     // variadic T t...) style
    Y     // variadic T t,...) style
    Z     // not variadic

(The current core.demangle which follows this wrong ABI documentation generates
the wrong output.)

Doc fix:

https://github.com/D-Programming-Language/d-programming-language.org/pull/17

Druntime is still _not_ fixed as
https://github.com/D-Programming-Language/druntime/commit/a9e774dde6fe55d43d72f5206e04d462b51b0ebd
