Unicode/UTF-8

Folks,

In a few days' time I will submit the SWIDTH0 patches to
mklocale/UTF-8.src and to hexdump/conv.c, posted here a couple of
weeks ago, for committing.

If anyone who's downloaded and tried them has any comments, the
next day or so would be a good time to email me.  I'm particularly
looking for feedback that I didn't inadvertently list any
non-zero-width characters as zero-width, and also that I didn't
miss any that are zero-width chars.

Links to those patches once more, are here:

In other related news, work is progressing on updating ncurses in
the base system to support wide chars, and work is also in progress
on addressing some of the issues noted for nvi.
