 1.10  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.
 1.9  09-Jun-2019  blymn branches: 1.9.12;
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.
 1.8  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.
 1.7  24-Apr-2019  blymn Add/improve debug output for some routines.
 1.6  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.

 1.5  07-Jan-2016  jdc branches: 1.5.14; 1.5.16;
Add missing new line in debug print.
 1.4  09-Nov-2013  blymn Rename the old __waddbytes function to _cursesi_waddbytes and add a
parameter that controls whether or not certain characters in the
string are interpreted or not (things like tab being expanded).

Make __waddbytes a wrapper for _cursesi_waddbytes that passes all
parameters and sets the flag for character interpretation for backward
compatibility.

Fix an incipient bug in _cursesi_waddbytes where garbage would have
been written to the terminal if the terminal TABSIZE was set > 8 and
character interpretation is on.

Convert all internal __waddbytes calls to use _cursesi_waddbytes, fix
the function prototypes and add a new flag that will be used later.

Fix the addchstr family functions so that they call _cursesi_waddbytes
with character interpretation off as per SUSV2.
 1.3  22-Jul-2009  roy branches: 1.3.6; 1.3.12;
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
 1.1.2.7  18-Mar-2007  jdc Make this compile without DEBUG defined.
 1.1.2.6  26-Feb-2007  blymn * commonalise adding a wide character so it can be reused
* make __waddbytes add wide characters if libcurses is built in wide
character mode.
* make waddch add wide characters if libcurses is built in wide character
mode.
 1.1.2.5  22-Jan-2007  jdc We only need to include <assert.h> when debugging.
 1.1.2.4  22-Jan-2007  blymn * Make WCHAR libcurses the default build
* Sprinkle about some SET_WCOL() calls where they were missing
 1.1.2.3  21-Jan-2007  jdc We need to include <assert.h> when debugging.
 1.1.2.2  21-Jan-2007  jdc Apply the changes that add debug "areas" on HEAD to the wcurses branch.
Add correspending changes to the debug code that is only present on the branch.
 1.1.2.1  21-Jan-2007  blymn Wide curses merge.
 1.3.12.1  20-Aug-2014  tls Rebase to HEAD as of a few days ago.
 1.3.6.1  22-May-2014  yamt sync with head.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs. ("Protocol error: too many arguments")
