Sorry, original machine that I sudo'd to root is CentOS 6; the machine
where it was acting weird was CentOS7. Terminal is rxvt, and my colors are
set everywhere to be the color Ghod (and IBM) meant them to be, green on
black. <g>

I'd been googling, and tried reset, and tried <ctrl-L>, and none of it
helped. I renamed /root/.viminfo, and tried vi -V, which showed it only
going after /etc/virc and /etc/vimrc, and neither modified. I also tried
vi --noplugin.
