+ fix several formatting issues with manual pages.
+ correct read of terminfo entry in which all strings are absent or
explicitly cancelled. Before this fix, the result was that all were
treated as only absent.
+ modify infocmp to suppress mixture of absent/cancelled capabilities
that would only show as "NULL, NULL", unless the -q option is used,
e.g., to show "-, @" or "@, -".
+ trim newlines, tabs and escaped newlines from terminfo "paths" passed
to db-iterator.
+ ignore zero-length files in db-iterator; these are useful for
instance to suppress "$HOME/.terminfo" when not wanted.
+ amended "b64:" encoder to work with the terminfo reader.
+ modify terminfo reader to accept "b64:" format using RFC-3548 in
as well as RFC-4648 url/filename-safe format.
+ modify terminfo reader to accept "hex:" format as generated by
"infocmp -0qQ1" (cf: 20150905).
+ adjust authors comment to reflect drop below 1% for SV.
+ minor comment-fixes to help automate links to bug-urls -TD
+ add dvtm, dvtm-256color -TD
+ add settings corresponding to xterm-keys option to tmux entry to
reflect upcoming change to make that option "on" by default
(patch by Nicholas Marriott).
+ uncancel Ms in tmux entry (Harry Gindi, Nicholas Marriott).
+ add dumb-emacs-ansi -TD
+ improve discussion of early history of tput program.
+ incorporate A_COLOR mask into COLOR_PAIR(), in case user application
provides an out-of-range pair number (report by Elijah Stone).
+ clarify description in tput manual page regarding support for
termcap names (prompted by FreeBSD #214709).
+ remove a restriction in tput's support for termcap names which
omitted capabilities normally not shown in termcap translations
(cf: 990123).
+ modify configure script for clang as used on FreeBSD, to work around
clang's differences in exit codes vs gcc.
+ improve discussion of early history of tset/reset programs.
+ clarify in manual pages that the optional verbose option level is
available only when ncurses is configured for tracing.
+ amend change from 20161231 to avoid writing traces to the standard
error after initializing the trace feature using the environment
variable.
+ amend changes for tput to reset tty modes to "sane" if the program
is run as "reset", like tset. Likewise, ensure that tset sends
either reset- or init-strings.
+ improve manual page descriptions of tput init/reset and tset/reset,
to make it easier to see how they are similar and different.
+ move a static result from key_name() to _nc_globals
+ modify _nc_get_screensize to allow for use_env() and use_tioctl()
state to be per-screen when sp-funcs are configured, better matching
the behavior when using the term-driver configuration.
+ improve cross-references in manual pages for often used functions
+ move SCREEN field for use_tioctl() data before the ncursesw fields,
and limit that to the sp-funcs configuration to improve termlib
compatibility (cf: 20120714).
+ correct order of initialization for traces in use_env() and
use_tioctl() versus first trace calls.
+ fix errata for ncurses-howto (report by Damien Ruscoe).
+ fix a few places in configure/build scripts where DESTDIR and rpath
were combined (report by Thomas Klausner).
+ merge current st description (report by Harry Gindi) -TD
+ modify flash capability for linux and wyse entries to put the delay
between the reverse/normal escapes rather than after -TD
+ modify program tabs to pass the actual tty file descriptor to
setupterm rather than the standard output, making padding work
consistently.
+ explain in clear's manual page that it writes to stdout.
+ add special case for verbose debugging traces of command-line
utilities which write to stderr (cf: 20161126).
+ remove a trace with literal escapes from skip_DECSCNM(), added in
20161203.
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ correct parmeters for copywin call in _nc_Synchronize_Attributes()
(patch by Leon Winter).
+ improve color-handling section in terminfo manual page (prompted by
patch by Mihail Konev).
+ modify programs clear, tput and tset to pass the actual tty file
descriptor to setupterm rather than the standard output, making
padding work.
+ modify tset -w (and tput reset) to update the program's copy of the
screensize if it was already set in the system, to improve tabstop
setting which relies upon knowing the actual screensize.
+ add functionality of tset -w to tput, like the "-c" feature this is
not optional in tput.
+ add "clear" as a possible link/alias to tput.
+ improve tput's check for being called as "init" or "reset" to allow
for transformed names.
+ split-out the "clear" function from progs/clear.c, share with
tput to get the same behavior, e.g., the E3 extension.
