A sudo-capable user can do all sorts of bad things while sudoing,
but that's not what we are talkin about.
Here the issue is what malicious code can do, while that user is NOT sudoing,
to arrange to take advantage later.  One way is by editing .emacs
so that it will do something bad next time the user runs Emacs under sudo.

Unfortunately, it seems there are many ways the code could do that,
which do not work by editing .emacs.  So trying to block that avenue
is ineffective.
