[Bug 1783162] Re: mvwin doesn't work if window is created with zero coordinates.

[Thomas Dickey]

It's in the manual page: the zero-coordinates produce a window as large
as the screen, and mvwin will not move it off the screen.

Bug description:
  Using the following code I cant move the window with mvwin
  ============================================================
  #include <ncurses.h>
  #include <stdlib.h>

  void quit();

  int main(int argc, char** argv) {
    initscr();
    atexit(quit);
    curs_set(0);
    noecho();

    WINDOW *win = newwin(0,0,0,0); // <-- Defference
    mvwin(win,10,10);
    wresize(win,10,10);

    refresh();
    box(win,0,0);
    wrefresh(win);
    getch();

    return 0;
  }

  void quit() {
    endwin();
  }

  Changing the window start coordinates to 1,1 and it works.

    atexit(quit);
    curs_set(0);
    noecho();

    WINDOW *win = newwin(1,1,0,0); // <-- Defference
    mvwin(win,10,10);
    wresize(win,10,10);

    refresh();
    box(win,0,0);
