+ modify keyname() to use "^X" form only if meta() has been called, or if keyname() is called without initializing curses, e.g., via initscr() or newterm() (prompted by LinuxBase #1604). + document some portability issues in man/curs_util.3x + add a shadow copy of TTY buffer to _nc_prescreen to fix applications broken by moving that data into SCREEN (cf: 20061230).
