 1.11  23-Dec-2024  blymn Sprinkle about some cycle wasting checks for the win pointer being
null. Unfortunately, ncurses does this and there is some sloppy code
out there that relies on the check resulting in segfaults in
NetBSD curses which then, of course, gets blamed for the error.
 1.10  25-Jan-2022  blymn branches: 1.10.4;
Correct (hopefully) the handling of wide characters.

* Remove the WCOL family of macros, these were "stealing" the upper bits
of a character attribute to store the column width of a character. No
warning was given about this in curses.h which meant it was easy to
accidentally reuse the bits in use by the WCOL macros (we already did).
Add couple of 16bit ints to the character structure iff HAVE_WCHAR is
true to hold the display width and wide char related flags (just
continuation at the moment)
* Convert all instances of WCOL macros to just reference the column width
in the char structure so it is not obfuscated.
* Fix cursor positioning so placing a cursor in the middle of a wide char
actually does just that.
* Fix plod so it understands that if the cursor is going to be positioned
in the middle of a wide char it cannot just reprint the char to get there.
* Fix plodput so it correctly counts the number of output characters for
wide characters.
* Fix slk routines to properly size the wctomb() buffer.
 1.9  15-Aug-2021  rillig libcurses: fix usage of __warn_references

Since that macro can expand to an empty token list, it adds its own
semicolon as needed. Removing the extra semicolon fixes the lint
warnings about empty declarations. These empty declarations are a GCC
extension.
 1.8  09-Jun-2019  blymn Rework previous fix for getch cursor position when cursor is moved
without refresh. If the window is not dirty but the window cursor
position does not match curscr then move the cursor. This fixes
the issues seen in PR lib/54263.
 1.7  20-May-2019  blymn Back out incorrect fix for PR 53617 and fix it in a different way.
Keep track of the cursor location, if getch is called without a refresh
and without pending updates (dirty windows) then move the cursor to the
correct location directly. Doing this prevents unnecessary refreshes.
 1.6  24-Feb-2019  roy Fix warn macro usage.

Thanks to rofl0r.
 1.5  22-Nov-2018  uwe Drop HAVE_WCHAR ifdefs from code that is not even compiled with !HAVE_WCHAR.

We still try to mainain the ability to build our curses with
!HAVE_WCHAR, but it doesn't make sense to provide stubs for new wide
API functions that just error out when !HAVE_WCHAR. Any code that
only uses old API (and can work with !HAVE_WCHAR curses) doesn't use
those new functions. The code that uses new API obviosly cannot work
when all the new API is stubbed out.

So the plan is to drop the stubs. This commit does that for files
that are not even compiled with !HAVE_WCHAR (not only those stubs are
useless, they were not even there to begin with).

Same object code is generated for the normal HAVE_WCHAR case. Nothing
is even recompiled for !HAVE_WCHAR.

 1.4  06-Jan-2017  roy branches: 1.4.12; 1.4.14;
KNF.
Normalise coding style.
White space police.
Sprinkle some extra braces to make the flow more clear.

No functional changes.
 1.3  22-Jul-2009  roy branches: 1.3.28;
Prepare curses for the possibility of changing from termcap to terminfo.
term.h #defines lines, pad_char and no_color_video macros which conflict
with existing curses code. We change lines to alines and nlines depending
on use, pad_char to padchar and no_color_video becomes no_color_attributes
but with a strong alias from no_color_video.
 1.2  28-May-2007  blymn Merge in wide curses code done as a Summer of Code project by
Ruibiao Qiu.
 1.1  21-Jan-2007  blymn branches: 1.1.2;
Wide curses merge
 1.1.2.1  21-Jan-2007  blymn Merge wide curses.
 1.3.28.1  07-Jan-2017  pgoyette Sync with HEAD. (Note that most of these changes are simply $NetBSD$
tag issues.)
 1.4.14.1  10-Jun-2019  christos Sync with HEAD
 1.4.12.1  26-Nov-2018  pgoyette Sync with HEAD, resolve a couple of conflicts
