patch to correct detection of fileencoding and to avoid disappeared some
symbols

In the newest port nvi-m17n (1.79.20040608_4,1), even when the previous patch I
uploaded (Comment 4) is applied, there is another problem; some well-used
multi-byte symbols, e.g. the circle symbol (ISO-2022-JP code 217b) or the
multiplication sign (215f), cannot be displayed.

I guess that this problem is related to ncursew library, although I could not
find the way to fix it.
However, this problem can be solved by using the bundled curses codes included
in the original ports sources instead of linking /lib/libncursesw.so.8.

The new patch is an accumulated patch to apply to nvi-m17n-1.79.20040608_4,1.
This can fix two problems.
One is to solve the detection error of fileencoding, which is same to the patch
uploaded previously (obsoleted).
The other is new patch to solve the disappearing the well-used symbols.
