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.

+ *
+ * Demonstrate the waddwstr() and wadd_wch functions.
+ * Thomas Dickey - 2009/9/12
+ *
+ * Note: to provide inputs for *add_wch(), we use setcchar(). A quirk of the
+ * X/Open definition for that function is that the string contains no
+ * characters with negative width. Any control character (such as tab) falls
+ * into that category. So it follows that *add_wch() cannot render a tab
+ * character because there is no legal way to construct a cchar_t containing
+ * one. X/Open does not document this, and it would be logical to assume that
+ * *addwstr() has the same limitation, but it uses a wchar_t string directly,
+ * and does not document how tabs are handled.
