ncurses 6.0 - patch
20170401
+ minor fixes for vt100+4bsd, e.g., delay in sgr for consistency -TD
+ add smso for env230, to match sgr -TD
+ remove p7/protect from sgr in fbterm -TD
+ drop setf/setb from fbterm; setaf/setab are enough -TD
+ make xterm-pcolor sgr consistent with other capabilities -TD
+ add rmxx/smxx ECMA-48 strikeout extension to tmux and xterm-basic
(discussion with Nicholas Marriott)
+ add test-programs sp_tinfo and extended_color
+ modify no-leaks code for lib_cur_term.c to account for the tgetent()
cache.
+ modify setupterm() to save original tty-modes so that erasechar()
works as expected. Also modify _nc_setupscreen() to avoid redundant
calls to get original tty-modes.
+ modify set_curterm() to update ttytype[] data used by longname().
+ modify wattr_set() and wattr_get() to return ERR if win-parameter is
null, as documented.
+ improve cast used for null-pointer checks in header macros, to
reduce compiler warnings.
+ modify several functions, using the reserved "opts" parameter to pass
color- and pair-values larger than 16-bits:
+ getcchar(), setcchar(), slk_attr_set(), vid_puts(), wattr_get(),
wattr_set(), wchgat(), wcolor_set().
+ Other functions call these with the corresponding altered behavior,
including chgat(), mvchgat(), mvwchgat(), slk_color_on(),
slk_color_off(), vid_attr().
+ add new functions for manipulating color- and pair-values larger
than 16-bits. These are extended_color_content(),
extended_pair_content(), extended_slk_color(), init_extended_color(),
init_extended_pair(), and the corresponding sp-funcs.
