Ah, but can you tell which one you will invoke *before* you invoke it?
That's the rub.  If you have to wait until afterward then a user would
really need to know the subtle details of all of them.  How do you
document this to a user in a way which will not be confusing to the
newbie and not tedious to the expert?  How can you write a unix manual
that would work across both the classic Sun, HP, IBM, AT&T, DEC, BSD
systems and also work on the more modern Free Software systems as too?

BTW I agree that most vi clones are "close enough for government work"
as they say.  While it frustrates me it should still be possible to
use them mostly effectively.  I was whining softly because I don't
like the result.  But I know we only got here because without a free
version of vi years ago that a clone was needed.  So I blame closed
source proprietary software for all of my troubles.  :-) :-)
