don't blink cursor on /dev/tty1

The docstring:
   blink-cursor-mode is an interactive compiled Lisp...
   Note that this command is effective only when Emacs
   displays through a window system, because then Emacs does its own
   cursor display.  On a text-only terminal, this is not implemented.

OK, but mention what a user should do in that case, as the blinking
could be driving him nuts and this is the only document he can find.

You could mention 'see also visible-cursor' as you do in Info. At
least that will give them a bar instead of a block cursor.

Indeed, /usr/share/doc/linux-doc-2.6.21/Documentation/VGA-softcursor.txt.gz
  To get red non-blinking block, use:    echo -e '\033[?17;0;64c'
And indeed
$ (sleep 4;echo -e '\033[?17;0;64c' > /dev/tty)&fg %emacs
works until one does anything in emacs.
In a *shell* window, echo -ne '\033[?17;0;64c' > /dev/tty1;sleep 3
gives 3 seconds of nonblinking pleasure.
