elvis is more improved than nvi from this description of nvi, though apparently
not as much as vim, considering vim installation takes about six times the disk
space required for elvis.  elvis has a lot of documentation in HTML files that
can be viewed from within elvis or from a web browser, much more than will fit
on a man page.  vim uses a different form of hypertext.

I suppose, if I want, I could download a Linux version of nvi, though not a DOS
version, and compile from source if I don't get a binary.

Didn't I say on the last message, I already downloaded vi man page from the web;
also downloaded man pages for ed, disklabel, wscons, mbrlabel, dosboot, boot and
some other things.  So I already have vi man page readable from DOS or Linux.

There are also some other vi clones or derivatives, including vile, which is an
awkward hybrid of vi and emacs, well named according to my first impressions.
