	Of course, one can prevent access to the shell through the editor
	using a number of techniques, viz: 1) If you have access to the
	editor source code, simply choose the no-shell option (we do this
	with the public-domain 'less' pager); 2) Using a binary editor or
	a suitable C program, overwrite relevant strings to prevent shell
	access.

	We've used the latter approach, together with a redefinition of
	SHELL to something innocuous on rsxtech, and no one has broken
	through yet.
