 *
 * Demonstrate the waddwchstr() 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
 * *addwchstr() has the same limitation, but it uses a wchar_t string directly,
 * and does not document how tabs are handled.
