Import a stock copy of ncurses 5.8 into the vendor space.vendor/ncurses/5.8-20110226
It seems both local changes we made to 5.7 have already been fixed upstream properly, so there is no need to preserve the changes. Also, with SVN we import full source trees. Unlike CVS, where we removed unneeded cruft.

+ * Name: Towers of Hanoi.
+ *
+ * Desc:
+ * This is a playable copy of towers of hanoi.
+ * Its sole purpose is to demonstrate my Amiga Curses package.
+ * This program should compile on any system that has Curses.
+ * 'hanoi' will give a manual game with 7 playing pieces.
+ * 'hanoi n' will give a manual game with n playing pieces.
+ * 'hanoi n a' will give an auto solved game with n playing pieces.
+ *
+ * Author: Simon J Raybould (sie@fulcrum.bt.co.uk).
+ * (This version has been slightly modified by the ncurses maintainers.)
+ *
+ * Date: 05.Nov.90
