+ 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'.
