Update to 1.2.20130523:

2013/05/23
	+ modify ifdef in arrows.c to work around packages which use the
	  wide-character ncursesw headers with the ncurses library (report
	  by Aleksey Cheusov).
	+ correct workaround for xterm alternate-screen to work with/without
	  the fix made in ncurses that makes putp() always write to the
	  standard output (Debian #708829).
	+ improve limit-checks for checklist, in case the dialog is resized
	  (report by Ilya A Arkhipov).
	+ add --last-key option (adapted from patch by Jordi Pujol, Debian
	  #697607).

2013/03/15
