With the recently rearranged code, it's easy to see that "this == NULL"
can't be true here:

note ->     if (!this->child)
            {   ...
                return correct_key_code (code);
            }
            if (!push_char (c))
            {   ...
                goto pend_send;
            }
            keylog (" push_char(%d) ok\n", c);
            parent = this;
never NULL->this = this->child;
            if (parent->action == MCKEY_ESCAPE && old_esc_mode)
            {
                if (no_delay)
                {
                    GET_TIME (esctime);
can't be true---->  if (this == NULL)

This patch removes that if().
