matching a newline ctrl-j

Hi,
For some reasons, I need to run some commands as
root and need to take root environment before running
those commands (most of them require arguments I am
unaware of).
Let's take an example with the "who" command
/etc/sudoers:
[...]
bob zeus: NOPASSWD: /usr/bin/su - root -c /usr/bin/who,/usr/bin/su - root
-c /usr/bin/who *,!/usr/bin/su - root -c /usr/bin/who *[;|^`&$><]*
[...]
Bob can use 'who' with or without arguments but he cannot add any
command by trying something like :
sudo /usr/bin/su -root "/usr/bin/who;id"
My problem is that I don't know how to avoid that ($ is the shell prompt) :
$sudo /usr/bin/su -root /usr/bin/who"[space]
> id"
bob pts/1 Dec 12 12:12 (X.X.X.X)
uid=0(root) gid=1(other)
$
Is there a way to match and deny any ctrl-j in the sudoers file ?
Is it normal that sudo gives arguments with ctrl-j (ie newlines)
to a command ?
Thank you in advance for your help.
