+ suppress ncv in screen entry, allowing underline (patch by Alejandro R Sedeno). + also suppress ncv in konsole-base -TD + fixes in wins_nwstr() and related functions to ensure that special characters, i.e., control characters are handled properly with the wide-character configuration. + correct a comparison in wins_nwstr() (Redhat #661506). + correct help-messages in some of the test-programs, which still referred to quitting with 'q'.

*
|
|
* Demonstrate the wins_wstr() and wins_wch functions.
|
|
* Thomas Dickey - 2002/11/23
|
|
*
|
|
* Note: to provide inputs for *ins_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 *ins_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
|
|
* *ins_wstr() has the same limitation, but it uses a wchar_t string directly,
|
|
* and does not document how tabs are handled.
