I am *fed* *up* with all these postings claiming that this problem is
due to this or that, for they all miss something!  It is really three
things put together:

1- TVI was silly enough to build a magic-cookie terminal,
2- There's no magic-cookie support in Gosmacs, and
3- Someone hacked out a TVI termcap entry carelessly.

The simplest way to fix it is to clean up the tvi termcap entry.  Get
rid of the silly \EG so and se strings and use \E( and \E) (bright and
dim).  Provided you never use protect mode, which is inappropriate for
Emacs anyway, this works fine (it's what we're using).

Replacing with GNUmacs is a much more drastic solution.  We have not
taken that route because there was no documentation on GNUmacs lisp and
the MockLisp converter broke on our local extensions to MLisp (we have
source and I have extended Gosmacs a good deal).  Absent the GNUmacs
lisp documentation there were just two choices:  rewrite it all from
scratch (which would have been difficult without the docs) or forget
GNUmacs.  We chose the latter. I'm not sorry, especially considering
how bizarre the keybindings of GNUmacs are to someone used to Gosmacs
(I mean, really, help on backspace?!  Pause on scroll-one-line-up?!).
