Update nvi to 2.2.0-05ed8b9

2020-10-01T04:46:23+00:00

This version incorporates many fixes in particular a fix for vi -w
Another approach was proposed to merge those fixes (see review), I find
it easier to track changes if we keep importing snapshot on regular
basis

nvi: fallback to ISO8859-1 as last resort

2020-06-13T14:11:02+00:00

Current logic of using user's locale encoding that is UTF-8 doesn't make
much sense if we already failed the looks_utf8() check and skipped
encoding set using "fileencoding" as being UTF-8 as well; fallback to
ISO8859-1 in that case.

Update nvi to 2.1.3 which fixes the data corruption when locale conversion

Update nvi-1.79 to 2.1.1-4334a8297f

2013-08-11T20:03:12+00:00

This is the gsoc-2011 project to clean up and backport multibyte support
from other nvi forks in a form we can use.

USE_WIDECHAR is on unless building for the rescue crunchgen. This should
allow editing in the native locale encoding.

USE_ICONV depends on make.conf having 'WITH_ICONV=YES' for now.  This
adds the ability to do things like edit a KOI8-R file while having $LANG
set to (say) en_US.UTF-8.  iconv is used to transcode the characters for
display.

Other points:
* It uses gencat and catopen/etc instead of homegrown msg catalog stuff.
* A lot of stuff has been trimmed out, eg: the perl and tcl bindings which
  we could never use in base anyway.
* It uses ncursesw when in widechar mode.  This could be interesting.
