[Bug 1021783] Re: invalid behavior of curses.newpad().refresh()

My debdiff shouldn't be necessary anymore. It is fixed in the debian
branch above (slightly differently), and it was fixed in python3.3 in
the recent quantal upload (with the same debian/patches/ncursesw-
configure.diff change).

Sorry, I should have removed the patch tag when I noticed the fix the
other day.

Title:
  invalid behavior of curses.newpad().refresh()

Status in “python3.2” package in Ubuntu:
  Confirmed

Bug description:
  There is invalid behavior of builtin curses module in amd64 version
  python3.2.

  From API spec, `refresh()` method of a window object returned by
  `curses.newpad(h,w)` should accept 6 arguments; `pad.refresh(pt, pl,
  st, sl, sb, sr)`.

  - http://docs.python.org/py3k/library/curses.html#curses.newpad

  But python3.2 package in amd64 ubuntu precise does not accept
  arguments.

  [bug occured snippet: newpad-refresh.py]
  ##########################################
  import curses

  try:
      screen = curses.initscr()
      curses.cbreak()

      pad = curses.newpad(10, 10)
      pad.addstr(0, 0, "press q")
      size = screen.getmaxyx()
      pad.refresh(0, 0, 0, 0, size[0] - 1, size[1] - 1)
      while True:
          ch = pad.getch()
          if ch == ord("q"):
              break
          pass
      pass
  finally:
      curses.nocbreak()
      curses.endwin()
      pass

  The code is worked well on python2.7 pakcage and self compiled python3.2.3.
  There may be a package build problem at python3.2 or ncurses.
