[C++ PATCH] Fix comment

[Nathan Sidwell]

In answering a question about passing non-trivial types through ..., I 
discovered a misleading comment.  It is NOT just like a value parm, 
because we don't locally copy it.

class X { ..,non-poddy... };
void Foo (X, ...);
void bin (X &p)
{
   Foo (p, p);
}
Only the first arg to Foo goes via a copy-constructor.

Fixed thusly and applied.
