The IFS stuff can be dealt with by patching the shell. Those with source
could easily add a putenv("IFS= \t\n") (or something equivalent) in some
convenient place to stop the shell from inheriting IFS.

If you don't have source, you could do what I did on a SVR2(-like) machine
I'm administrating. Write a small program that simply does:
		putenv("IFS= \t\n");
		execv("/bin/.real-sh", argv);
and call it /bin/sh. (you mv'd /bin/sh to /bin/.real-sh before of course!).
This works Ok on my machine. Does anybody know of any reasons why somehting
like this shouldn't be done?

How?
