history issue - bug?

[Hans <hans.ullrich@loop.de>]

Hi folks, 

try this:

1. login as normal user

2. become root with "su -"

3. delete history with "history -c"

4. Check history, history is gone

5. logout from root by "CTL + D" or "exit"

6. relogin as root with "su -"

7. Check history, voila, it appears again.

What is wrong? Is it a bug or am I doing the wrong way?

Any comment will help.

Best regards

Hans
