Do not bother passing optional argument to WriteConsoleA. 

Passing a pointer to a local variable to WriteConsoleA is
not actually needed if we're not going to do anything with
what WriteConsoleA would put in there.

For the wpbuf class the pointer argument was made optional,
so it can be just left out; other call places now pass a
NULL pointer instead.  The local variables `wn' and `n'
are no unused, so they go away.
