bug#5817: "false" core util

[phoenix]

Hey guys,
I've found a serious error in the program "false": If I pipe some text to it
(e.g. echo "i lost the game" | false), it does not fail but rather returns a
success. Any suggestions? I need this program very much for completing my
thesis on Pseudo-Riemannian manifolds.
It would very kind of you if you'd inform me when the error has been fixed.
(Remark: I am using Ubuntu 9.10.)
Best regards,
Hajo Pei
