ab35868474 It is ridiculous to truncate files on character conversions without 
warning and a chance for recovery. This patch sets the handler to
copy the character, clear the error and proceed instead of bailing
out.

To replicate:
	- unset LANG
	- Create a file that has ~1000 lines. Put a single bad character
	- '\344' in it, around 2/3rds of the file down. Save it.
	- export LANG=en_US.UTF-8
	- edit the file. Notice there is no error for input conversion,
	  since nvi reads the file opportunistically.
	- :w Boom, the file is truncated.

Alternatively, you can put that character in the first line of the file,
and watch the fireworks. If you like to restore the previous behavior
compile with -DERROR_ON_CONVERT

XXX: Pullup to 6, 5 etc.

Restore lost fix:
    http://mail-index.netbsd.org/source-changes/2001/09/09/0042.html

Define ENTIRE_LINE to be -1 instead of 0 since we may want to copy 0 characters.
(and use ENTIRE_LINE instead of 0 where appropriate)

This fixes a bug in the dw command with for example:

<cursor>
a b c

~
~
if you hit dw there, only the empty line would be killed but both the empty
line and the subsequent one would be pasted when asked for with P for example.

80356df9b8 1. fix PR/44455, nonprintable character doesn't show hex-visual 
under big endian.
2. ":set octal" with nonprintable character causes nbwcurses move error.
3. moving (big)words by wW/eE/bB can't handle non-ascii characters.
4. toggle uppercase/lowercase by ~ can't handle non-ascii characters.
5. don't feed CHAR_T(=wchar_t) to is* function directly.
   is* funcs with over UCHAR_MAX value may cause undefined behavior.
   some ctype implementation(such as FreeBSD) return unexpected
   result(same result as isw* func).
6. using non-ascii digit character with count/line number of ex/vi
   command may causes unexpeced result.

This brings about least astonishment for users, permittings tags
