Import a stock copy of ncurses 5.8 into the vendor space.vendor/ncurses/5.8-20110226
It seems both local changes we made to 5.7 have already been fixed upstream properly, so there is no need to preserve the changes. Also, with SVN we import full source trees. Unlike CVS, where we removed unneeded cruft.

-<H1>Announcing ncurses 5.7</H1>
-
-The ncurses (new curses) library is a free software emulation of
-curses in System V Release 4.0, and more. It uses terminfo format,
-supports pads and color
-and multiple highlights and forms characters and function-key mapping,
-and has all the other SYSV-curses enhancements over BSD curses.<P>
-
-In mid-June 1995, the maintainer of 4.4BSD curses declared that he
-considered 4.4BSD curses obsolete, and encouraged the keepers of
-Unix releases such as BSD/OS, FreeBSD and NetBSD to switch over to
-ncurses.<P>
-
-The ncurses code was developed under GNU/Linux.
-It has been in use for some time with OpenBSD as the system curses library,
-and on FreeBSD and NetBSD as an external package.
-It should port easily to any ANSI/POSIX-conforming UNIX.
-It has even been ported to OS/2 Warp!<P>
-
-The distribution includes the library and support utilities, including a
-terminfo compiler tic(1), a decompiler infocmp(1), clear(1), tput(1), tset(1),
-and a termcap conversion tool captoinfo(1). Full manual pages are provided for
-the library and tools.<P>
-
-The ncurses distribution is available via anonymous FTP at
-the GNU distribution site
-<A HREF="ftp://ftp.gnu.org/gnu/ncurses/">ftp://ftp.gnu.org/gnu/ncurses/</A>&nbsp;.
-<br>It is also available at

-<H1>Release Notes</H1>
-
-This release is designed to be upward compatible from ncurses 5.0 through 5.6;
-very few applications will require recompilation, depending on the platform.
-These are the highlights from the change-log since ncurses 5.6 release.
-<p>
-Interface changes:
-<ul>
- <li>generate linkable stubs for some macros:
- <br>
- getattrs
-
-</ul>
-New features and improvements:
-<ul>
- <li>library
- <ul>
- <li>new flavor of the ncurses library provides rudimentary
- support for POSIX threads. Several functions are
- reentrant, but most require either a window-level or
- screen-level mutex.<br>
- (This is <em>API</em>-compatible,
- but not <em>ABI</em>-compatible with the normal library).
-
- <li>add <code>NCURSES_OPAQUE</code> symbol to curses.h, will
- use to make structs opaque in selected configurations.
-
- <li>add <code>NCURSES_EXT_FUNCS</code> and
- <code>NCURSES_EXT_COLORS</code> symbols to curses.h to make
- it simpler to tell if the extended functions and/or colors
- are declared.
-
- <li>add wresize() to C++ binding
-
- <li>eliminate fixed-buffer vsprintf() calls in C++ binding.
-
- <li>add several functions to C++ binding which wrap C functions
- that pass a WINDOW* parameter.
-
- <li>adapt mouse-handling code from menu library in form-library
-
- <li>improve tracing for form library, showing created forms,
- fields, etc.
-
- <li>make $NCURSES_NO_PADDING feature work for termcap interface .
-
- <li>add check to trace-file open, if the given name is a
- directory, add ".log" to the name and try again.
-
- <li>several new manpages: curs_legacy.3x, curs_memleaks.3x,
- curs_opaque.3x and curs_threads.3x
- </ul>
-
- <li>programs:
- <ul>
- <li>modified three test-programs to demonstrate the threading
- support in this version: ditto, rain, worm.
-
- <li>several new test-programs: demo_panels, dots_mvcur,
- inch_wide, inchs, key_name, key_names, savescreen,
- savescreen.sh test_arrays, test_get_wstr, test_getstr,
- test_instr, test_inwstr and test_opaque.
-
- <li>add <code>adacurses-config</code> to the Ada95 install.
-
- <li>modify tic <code>-f</code> option to format spaces as
- <code>\s</code> to prevent them from being lost when that
- is read back in unformatted strings.
-
- <li>The <code>tack</code> program is now distributed separately
- from ncurses.
- </ul>
-
- <li>terminal database
- <ul>
- <li>added entries:
- <ul>
- <li><code>Eterm-256color</code>,
- <code>Eterm-88color</code> and
- <code>rxvt-88color</code>
- <li><code>aterm</code>
- <li><code>konsole-256color</code>
- <li><code>mrxvt</code>
- <li><code>screen.mlterm</code>
- <li><code>screen.rxvt</code>
- <li><code>teraterm4.59</code> is now the primary primary
- teraterm entry, renamed original to
- <code>teraterm2.3</code>
- <li><code>9term</code> terminal
- <li>Newbury Data entries
- </ul>
- <li>updated/improved entries:
- <ul>
- <li><code>gnome</code> to version 2.22.3
- <li><code>h19</code>, <code>z100</code>
- <li><code>konsole</code> to version 1.6.6
- <li><code>mlterm</code>, <code>mlterm+pcfkeys</code>
- <li><code>xterm</code>, and building-blocks for function-keys
- to <a href="http://invisible-island.net/xterm/xterm.log.html#xterm_230">xterm patch #230</a>.
- </ul>
- </ul>
-</ul>
-Major bug fixes:
-<ul>
- <li>add logic to tic for cancelling strings in user-defined
- capabilities
- (this is <em>needed</em> for
- current <code>konsole</code> terminfo entry).
-
- <li>modify <code>mk-1st.awk</code> so the generated makefile rules for
- linking or installing shared libraries do not first remove the
- library, in case it is in use, e.g., <code>libncurses.so</code> by
- <code>/bin/sh</code>.
-
- <li>correct check for notimeout() in wgetch().
-
- <li>fix a sign-extension bug in infocmp's repair_acsc() function.
-
- <li>change winnstr() to stop at the end of the line.
-
- <li>make Ada95 demo_panels() example work.
-
- <li>fix for adding a non-spacing character at the beginning of a line.
-
- <li>fill in extended-color pair to make colors work
- for wide-characters using extended-colors.
-
- <li>improve refresh of window on top of multi-column characters,
- taking into account split characters on left/right window
- boundaries.
-
- <li>modify <code>win_wchnstr()</code> to ensure that only a base cell
- is returned for each multi-column character.
-
- <li>improve <code>waddch()</code> and <code>winsch()</code> handling of
- EILSEQ from <code>mbrtowc()</code> by using <code>unctrl()</code>
- to display illegal bytes rather than trying to append further bytes
- to make up a valid sequence.
-
- <li>restore <code>curs_set()</code> state after
- <code>endwin()</code>/<code>refresh()</code>
-
- <li>modify <code>keyname()</code> to use "^X" form only if
- <code>meta()</code> has been called, or if <code>keyname()</code>
- is called without initializing curses, e.g., via
- <code>initscr()</code> or <code>newterm()</code>.
-
- <li>modify <code>unctrl()</code> to check codes in 128-255 range versus
- <code>isprint()</code>.
- If they are not printable, and locale was set, use a "M-" or "~"
- sequence.
-
- <li>improve <code>resizeterm()</code> by moving ripped-off lines, and
- repainting the soft-keys.
-
- <li>modify form library to accept control characters such as newline
- in set_field_buffer(), which is compatible with Solaris.
-
- <li>use <code>NCURSES_MOUSE_MASK()</code> in definition of
- <code>BUTTON_RELEASE()</code>, etc., to make those work properly
- with the <code>--enable-ext-mouse</code> configuration
-
- <li>correct some functions in Ada95 binding which were using return
- value from C where none was returned.
-
- <li>reviewed/fixed issues reported by Coverity and Klocwork tools.

+ <code>setaf</code>/<code>setab</code> strings from
+ <code>xterm+256color</code> and <code>xterm+88color,</code> and
+ provide a reduced version which works with termcap.</li>
+ </ul>
+
+ <h3>Terminal Database</h3>
+
+ <ul>

+ from FreeMiNT.</li>
+
+ <li>repurpose <code>gnome</code> terminfo entries as

+ </ul>
+ </li>
+ </ul>
+
+ <h2>Major bug fixes</h2>
+
+ <ul>
+ <li>ncurses library
+
+ <ul>
+ <li>wide character support
+
+ <ul>
+ <li>modify length returned by <code>getcchar</code> to
+ count the trailing null which is documented in
+ X/Open.</li>
+
+ <li>fix an infinite recursion when adding a
+ legacy-coding 8-bit value using
+ <code>insch</code>.</li>
+
+ <li>improve a workaround in adding wide-characters,
+ when a control character is found. The library uses
+ <code>unctrl</code> to obtain a printable version of
+ the control character, but was not passing color or
+ video attributes.</li>
+
+ <li>modify <code>waddch_literal</code>, updating
+ line-pointer after a multicolumn character is found to
+ not fit on the current row, and wrapping is done. Since
+ the line-pointer was not updated, the wrapped
+ multicolumn character was written to the beginning of
+ the current row.</li>
+
+ <li>fixes in <code>wins_nwstr</code> and related
+ functions to ensure that special characters, i.e.,
+ control characters are handled properly with the
+ wide-character configuration.</li>
+
+ <li>correct internal <code>_nc_insert_ch</code> to use
+ <code>_nc_insert_wch</code> when inserting wide
+ characters, since the <code>wins_wch</code> function
+ that it used did not update the cursor position.</li>
+ </ul>
+ </li>
+
+ <li>mouse
+
<ul>
- <li>new options:
- <dl>
-
- <dt>--disable-big-strings
- <dd>control whether static string tables are generated as single
- large strings (to improve startup performance), or as array
- of individual strings.
-
- <dt>--disable-relink
- <dd>control whether shared libraries are relinked (during install)
- when rpath is enabled.
-
- <dt>--disable-tic-depends
- <dd>make explicit whether tic library depends on ncurses/ncursesw
- library.
-
- <dt>--enable-mixed-case
- <dd>override the configure script's check if the filesystem
- supports mixed-case filenames.
- This allows one to control how the terminal database
- maps to the filesystem.
- For filesystems that do not support mixed-case, the library
- uses generate 2-character (hexadecimal) codes for the
- lower-level of the filesystem terminfo database
-
- <dt>--enable-reentrant
- <dd>builds a different flavor of the ncurses library (ncursest)
- which improves reentrant use of the
- library by reducing global and static variables
- (see the "--with-pthread" option for the threaded support).
-
- <dt>--enable-weak-symbols
- <dd>use weak-symbols for linking to the POSIX thread library,
- and use the same soname for the ncurses shared library
- as the normal library (caveat: the ABI is for the threaded
- library, which makes global data accessed via functions).
-
- <dt>--with-pthread
- <dd>build with the POSIX thread library (tested with AIX,
- Linux, FreeBSD, OpenBSD, HPUX, IRIX64, Solaris, Tru64).
-
- <dt>--with-ticlib
- <dd>build/install the tic-support functions in a separate library
-
- </dl>
-
- <li>improved options:
- <dl>
-
- <dt>--enable-ext-colors
- <dd>requires the wide-character configuration.
-
- <dt>--with-chtype
- <dd>ignore option value "unsigned" is always added to
- the type in curses.h; do the same for --with-mmask-t.
-
- <dt>--with-dmalloc
- <dd>build-fix for redefinition of <code>strndup</code>.
-
- <dt>--with-hashed-db
- <dd>accepts a parameter which is the install-prefix of a given
- Berkeley Database.
-
- <dt>--with-hashed-db
- <dd>the $LIBS environment variable overrides the search for the db
- library.
-
- <dt>--without-hashed-db
- <dd>assumed when "--disable-database" is used.
-
- </dl>
-
- </ul>
-
- <li>other configure/build issues:
- <ul>
- <li>build-fixes for LynxOS
- <li>modify shared-library rules to allow FreeBSD 3.x to use rpath.
- <li>build-fix for FreeBSD "contemporary" TTY interface.
- <li>build-fixes for AIX with libtool.
- <li>build-fixes for Darwin and libtool.
- <li>modify BeOS-specific ifdef's to build on Haiku.
- <li>corrected gcc options for building shared libraries on Solaris
- and IRIX64.
- <li>change shared-library configuration for OpenBSD, make rpath work.
- <li>build-fixes for using libutf8, e.g., on OpenBSD 3.7
- <li>add "-e" option in ncurses/Makefile.in when generating source-files
- to force earlier exit if the build environment fails unexpectedly.
- <li>add support for shared libraries for QNX.
- <li>change delimiter in <code>MKlib_gen.sh</code> from '%' to '@', to
- avoid substitution by IBM xlc to '#' as part of its extensions to
- digraphs.
- </ul>
-
- <li>library:
- <ul>
- <li>rewrite wrapper for <code>wcrtomb()</code>, making it work on
- Solaris. This is used in the form library to determine the length
- of the buffer needed by <code>field_buffer</code>.
- <li>add/use configure script macro CF_SIG_ATOMIC_T, use the corresponding
- type for data manipulated by signal handlers.
- <li>set locale in misc/ncurses-config.in since it uses a range
- <li>disable GPM mouse support when $TERM does not happen to contain
- "linux", since Gpm_Open() no longer limits its assertion to terminals
- that it might handle, e.g., within "screen" in xterm.
- <li>reset mouse file-descriptor when unloading GPM library.
- </ul>
-
- <li>test programs:
- <ul>
- <li>update test programs to build/work with various UNIX curses for
- comparisons.
- </ul>
-</ul>

-
-<UL>
-<LI>All 257 of the SVr4 calls have been implemented (and are documented).
-<LI>Full support for SVr4 curses features including keyboard mapping, color,

-<UL>
-<LI>The API is 8-bit clean and base-level conformant with the X/OPEN curses
-specification, XSI curses (that is, it implements all BASE level features,
-and most EXTENDED features).
-It includes many function calls not supported under SVr4 curses
-(but portability of all
-calls is documented so you can use the SVr4 subset only).
-<LI>Unlike SVr3 curses, ncurses can write to the rightmost-bottommost corner
-of the screen if your terminal has an insert-character capability.
-<LI>Ada95 and C++ bindings.
-<LI>Support for mouse event reporting with X Window xterm
-and FreeBSD and OS/2 console windows.
-<LI>Extended mouse support via Alessandro Rubini's gpm package.
-<LI>The function <CODE>wresize()</CODE> allows you to resize windows, preserving
-their data.
-<LI>The function <CODE>use_default_colors()</CODE> allows you to
-use the terminal's default colors for the default color pair,
-achieving the effect of transparent colors.
-<LI>The functions <CODE>keyok()</CODE>
-and <CODE>define_key()</CODE> allow
-you to better control the use of function keys,
-e.g., disabling the ncurses KEY_MOUSE,
-or by defining more than one control sequence to map to a given key code.
-<LI>Support for 256-color terminals, such as modern xterm, when configured
-using the <code>--enable-ext-colors</code> option.
-<LI>Support for 16-color terminals, such as aixterm and modern xterm.
-<LI>Better cursor-movement optimization. The package now features a
-cursor-local-movement computation more efficient than either BSD's
-or System V's.
-<LI>Super hardware scrolling support. The screen-update code incorporates
-a novel, simple, and cheap algorithm that enables it to make optimal
-use of hardware scrolling, line-insertion, and line-deletion
-for screen-line movements. This algorithm is more powerful than
-the 4.4BSD curses quickch() routine.
-<LI>Real support for terminals with the magic-cookie glitch. The
-screen-update code will refrain from drawing a highlight if the magic-
-cookie unattributed spaces required just before the beginning and
-after the end would step on a non-space character. It will
-automatically shift highlight boundaries when doing so would make it
-possible to draw the highlight without changing the visual appearance
-of the screen.
-<LI>It is possible to generate the library with a list of pre-loaded
-fallback entries linked to it so that it can serve those terminal types even
-when no terminfo tree or termcap file is accessible (this may be useful
-for support of screen-oriented programs that must run in single-user mode).
-<LI>The tic(1)/captoinfo utility provided with ncurses has the
-ability to translate many termcaps from the XENIX, IBM and
-AT&amp;T extension sets.
-<LI>A BSD-like tset(1) utility is provided.
-<LI>The ncurses library and utilities will automatically read terminfo
-entries from $HOME/.terminfo if it exists, and compile to that directory
-if it exists and the user has no write access to the system directory.
-This feature makes it easier for users to have personal terminfo entries
-without giving up access to the system terminfo directory.
-<LI>You may specify a path of directories to search for compiled
-descriptions with the environment variable TERMINFO_DIRS (this
-generalizes the feature provided by TERMINFO under stock System V.)
-<LI>In terminfo source files, use capabilities may refer not just to
-other entries in the same source file (as in System V) but also to
-compiled entries in either the system terminfo directory or the user's
-$HOME/.terminfo directory.
-<LI>A script (<STRONG>capconvert</STRONG>) is provided to help BSD users
-transition from termcap to terminfo. It gathers the information in a
-TERMCAP environment variable and/or a ~/.termcap local entries file
-and converts it to an equivalent local terminfo tree under $HOME/.terminfo.
-<LI>Automatic fallback to the /etc/termcap file can be compiled in
-when it is not possible to build a terminfo tree. This feature is neither
-fast nor cheap, you don't want to use it unless you have to,
-but it's there.
-<LI>The table-of-entries utility <STRONG>toe</STRONG> makes it easy for users to
-see exactly what terminal types are available on the system.
-<LI>The library meets the XSI requirement that every macro entry
-point have a corresponding function which may be linked (and will be
-prototype-checked) if the macro definition is disabled with
-<CODE>#undef</CODE>.
-<LI>An HTML "Introduction to Programming with NCURSES" document provides
-a narrative introduction to the curses programming interface.

-
-<H1>State of the Package</H1>
-
-Numerous bugs present in earlier versions have been fixed; the
-library is far more reliable than it used to be. Bounds checking in many
-`dangerous' entry points has been improved. The code is now type-safe
-according to gcc -Wall. The library has been checked for malloc leaks and
-arena corruption by the Purify memory-allocation tester.<P>

-The ncurses code has been tested with a wide variety of applications
-including (versions starting with those noted):

+
+ <h1>Features of Ncurses</h1>The ncurses package is fully
+ compatible with SVr4 (System V Release 4) curses:
+
+ <ul>
+ <li>All 257 of the SVr4 calls have been implemented (and are
+ documented).</li>
+
+ <li>Full support for SVr4 curses features including keyboard
+ mapping, color, forms-drawing with ACS characters, and
+ automatic recognition of keypad and function keys.</li>
+
+ <li>An emulation of the SVr4 panels library, supporting a stack
+ of windows with backing store, is included.</li>
+
+ <li>An emulation of the SVr4 menus library, supporting a
+ uniform but flexible interface for menu programming, is
+ included.</li>
+
+ <li>An emulation of the SVr4 form library, supporting data
+ collection through on-screen forms, is included.</li>
+
+ <li>Binary terminfo entries generated by the ncurses tic(1)
+ implementation are bit-for-bit-compatible with the entry format
+ SVr4 curses uses.</li>
+
+ <li>The utilities have options to allow you to filter terminfo
+ entries for use with less capable
+ <strong>curses</strong>/<strong>terminfo</strong> versions such
+ as the HP/UX and AIX ports.</li>
+ </ul>The ncurses package also has many useful extensions over
+ SVr4:
+
+ <ul>
+ <li>The API is 8-bit clean and base-level conformant with the
+ X/OPEN curses specification, XSI curses (that is, it implements
+ all BASE level features, and most EXTENDED features). It
+ includes many function calls not supported under SVr4 curses
+ (but portability of all calls is documented so you can use the
+ SVr4 subset only).</li>
+
+ <li>Unlike SVr3 curses, ncurses can write to the
+ rightmost-bottommost corner of the screen if your terminal has
+ an insert-character capability.</li>
+
+ <li>Ada95 and C++ bindings.</li>
+
+ <li>Support for mouse event reporting with X Window xterm and
+ FreeBSD and OS/2 console windows.</li>
+
+ <li>Extended mouse support via Alessandro Rubini's gpm
+ package.</li>
+
+ <li>The function <code>wresize</code> allows you to resize
+ windows, preserving their data.</li>
+
+ <li>The function <code>use_default_colors</code> allows you to
+ use the terminal's default colors for the default color pair,
+ achieving the effect of transparent colors.</li>
+
+ <li>The functions <code>keyok</code> and
+ <code>define_key</code> allow you to better control the use of
+ function keys, e.g., disabling the ncurses KEY_MOUSE, or by
+ defining more than one control sequence to map to a given key
+ code.</li>
+
+ <li>Support for 256-color terminals, such as modern xterm, when
+ configured using the <code>--enable-ext-colors</code>
+ option.</li>
+
+ <li>Support for 16-color terminals, such as <em>aixterm</em>
+ and <em>modern xterm</em>.</li>
+
+ <li>Better cursor-movement optimization. The package now
+ features a cursor-local-movement computation more efficient
+ than either BSD's or System V's.</li>
+
+ <li>Super hardware scrolling support. The screen-update code
+ incorporates a novel, simple, and cheap algorithm that enables
+ it to make optimal use of hardware scrolling, line-insertion,
+ and line-deletion for screen-line movements. This algorithm is
+ more powerful than the 4.4BSD curses <code>quickch</code>
+ routine.</li>
+
+ <li>Real support for terminals with the magic-cookie glitch.
+ The screen-update code will refrain from drawing a highlight if
+ the magic- cookie unattributed spaces required just before the
+ beginning and after the end would step on a non-space
+ character. It will automatically shift highlight boundaries
+ when doing so would make it possible to draw the highlight
+ without changing the visual appearance of the screen.</li>
+
+ <li>It is possible to generate the library with a list of
+ pre-loaded fallback entries linked to it so that it can serve
+ those terminal types even when no terminfo tree or termcap file
+ is accessible (this may be useful for support of
+ screen-oriented programs that must run in single-user
+ mode).</li>
+
+ <li>The tic(1)/captoinfo utility provided with ncurses has the
+ ability to translate many termcaps from the XENIX, IBM and
+ AT&amp;T extension sets.</li>
+
+ <li>A BSD-like tset(1) utility is provided.</li>
+
+ <li>The ncurses library and utilities will automatically read
+ terminfo entries from $HOME/.terminfo if it exists, and compile
+ to that directory if it exists and the user has no write access
+ to the system directory. This feature makes it easier for users
+ to have personal terminfo entries without giving up access to
+ the system terminfo directory.</li>
+
+ <li>You may specify a path of directories to search for
+ compiled descriptions with the environment variable
+ TERMINFO_DIRS (this generalizes the feature provided by
+ TERMINFO under stock System V.)</li>
+
+ <li>In terminfo source files, use capabilities may refer not
+ just to other entries in the same source file (as in System V)
+ but also to compiled entries in either the system terminfo
+ directory or the user's $HOME/.terminfo directory.</li>
+
+ <li>A script (<strong>capconvert</strong>) is provided to help
+ BSD users transition from termcap to terminfo. It gathers the
+ information in a TERMCAP environment variable and/or a
+ ~/.termcap local entries file and converts it to an equivalent
+ local terminfo tree under $HOME/.terminfo.</li>
+
+ <li>Automatic fallback to the /etc/termcap file can be compiled
+ in when it is not possible to build a terminfo tree. This
+ feature is neither fast nor cheap, you don't want to use it
+ unless you have to, but it's there.</li>
+
+ <li>The table-of-entries utility <strong>toe</strong> makes it
+ easy for users to see exactly what terminal types are available
+ on the system.</li>
+
+ <li>The library meets the XSI requirement that every macro
+ entry point have a corresponding function which may be linked
+ (and will be prototype-checked) if the macro definition is
+ disabled with <code>#undef</code>.</li>
+
+ <li>An HTML "Introduction to Programming with NCURSES" document
+ provides a narrative introduction to the curses programming
+ interface.</li>
+ </ul>
+
+ <h1>State of the Package</h1>Numerous bugs present in earlier
+ versions have been fixed; the library is far more reliable than
+ it used to be. Bounds checking in many `dangerous' entry points
+ has been improved. The code is now type-safe according to gcc
+ -Wall. The library has been checked for malloc leaks and arena
+ corruption by the Purify memory-allocation tester.
+
+ <p>The ncurses code has been tested with a wide variety of
+ applications including (versions starting with those noted):</p>
