Also, add the functions :
use_default_colors();
assume_default_colors(fore, back);
(from ncurses) that allow the terminal default colours or user-specified
default colours to be used.
* Don't bother comparing lines that are not dirty when looking for the top
and bottom regions.
* In the loop that searches for the largest equal region, do the totally
half-assed hack of splitting the inner loop into two parts -- comparing
only the hash values the first time, and doing memcmp()s the second time.
This makes many of my test cases >100x as fast.
XXX This code needs a lot more work.
and the previous wrefresh() code is split between them. Background character
and attribute handling is now done in wnoutrefresh(), thus simplifying the code
in doupdate(), makech() and quickch().
Refine xterm workround and test for it earlier - this cuts down the number of
lines we test when looking for a scrolled region.
Rename unsetattr() to __unsetattr(), so it can be used by __stopwin().
(this is a requirement of SUSv2) - the old macro behaviour can be
restored by defining _CURSES_USE_MACROS.
Changed function prototypes to use ANSI style.
All externally visible functions now have ANSI style declarations.
of the SYSV curses facilities. The added features are the collapsing
of arrow and function keysequences (as defined by termcap for the
terminal) into symbolic code returns thus relieving the application of
recognising multi-character key sequences. Other features are the
capability to perform a timed wait for a key (good for when you are
not sure if there is a keypress ready or not) and the capability for
turning off the inter-key timeout when assembling multi-character
function keys.
this work was done by Julian Coleman <J.D.Coleman@newcastle.ac.uk>
and blymn@baea.com.au (Brett Lymn). i'm just integrating it. thanks
HEAPS guys!
Standard curses library use eight bit for standout mode, so
8-bit characters displays like highlighted 7-bit characters.
This patch produce library which is fully compatible with all curses
programs and add 8-bit chars to all input/display functions.
---
I don't think, that any programs wish to use internal curses
attribute _STANDOUT directly, in expressions like:
addch( ch | _STANDOUT );
Normal interface use standout() and standend() functions instead.
Many programs use 'char' type (with sign extention) for input characters
and sign extention becomes _STANDOUT mode in this case.
So, I refuse this future and allow 8-bit characters for programs,
which is designed for 7-bit only ('char' type using instead of
'unsigned char').

This small patch fix unpleasant standard curses bug:
curses can't expand TAB at all (but tries).
A man who wrote this curses misplace SYNC_IN and SYNCH_OUT,
this patch exchange macro calls.
This patch useful for standard 7-bit curses too, for this
you must delete '_' symbol before waddbytes and apply patch.

Oh, NO! This curses are really buggy!
This small patch fix following problem:
[ assumed scrollok(stdscr, TRUE) ]
when addch(ch) at lower right corner of screen, curses are realy
gone mad instead if simple scrolling... Curses code assumed that
this will be done correctly, but implement it with two bugs.
