If you have "set nomesg" in your .exrc file or your EXINIT parameter,
then vi notes the tty writability on entry.  Then any time it is in
visual mode, it will turn writes to the tty off, restoring the
original setting when escaping to ex mode, the shell, or quiting.

If I recall properly, changing the setting of mesg after entering
the editor is ineffective even though "set all" shows "nomesg".
