- renamed get_colorized_line() to generic_get_colorized_line - added get_non_colorized_line() for uncolored modes - renamed EditState::get_colorized_line_func to get_colorized_line make this function pointer always non NULL fixed bug in global-set-key: current bindings could not be overloaded better tty charset detection and handling: - always use utf8 when output is not a tty - allow override with -c CHARSET command line option - added state variable show-unicode to display non latin1 as \uXXXX - added command line argument -c CHARSET (--ttycharset) to specify the charset of the tty. tty charset is reported in *messages* buffer at startup - display unsupported glyphs as half-width or full-width question mark pairs improved tty output: use kill_end_of_line escape sequence
