[Precise SRU Justification]
Valid python programs using the refresh method with the optional arguments on a curses.newpad object will fail with a similar exception:
Traceback (most recent call last):
File "newpad-refresh.py", line 10, in <module>
pad.refresh(0, 0, 0, 0, size[0] - 1, size[1] - 1)
TypeError: refresh() takes exactly 0 arguments (6 given)
This breaks at least one of the examples in the python documentation and I believe limits the usefulness of the pad object, since it allows one to only display a portion of the pad with the refresh method.
[Fix]
Updates the ncursesw-include.diff patch with the version in quantal, adding /usr/include/ncursesw/ to the search path in configure.in. This allows the build scripts to find curses and builds the curses module with the correct number of arguments to refresh.
[Regression Potential]
The regression potential should be minor since it just enables a build option already enabled on the python2.7 package (as well as python3.2 and python3.3 in quantal).
[Test Case]
Running the following code with python3 will produce the above exception without the patch, and prompt to "press q" to quit the script with the patch.

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

===============================================================================
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.
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.
