ncurses 5.9 - patch 20140629

+ correct check in win_driver.c for saving screen contents, e.g., when
  NCURSES_CONSOLE2 is set (cf: 20140503).
+ reorganize b/B menu items in ncurses.c, putting the test-strings into
  subwindows.  This is needed for a planned change to use Unicode
  fullwidth characters in the test-screens.
+ correct update to form status for _NEWTOP, broken by fixes for
  compiler warnings (patch by Leon Winter, cf: 20120616).
