BUG: su to root

["Paul Murray" <pmurray@indigo.ie>]

Problem:

When doing su to root my zsh_histroy file is set to zero and the 
owner of the file is set to root.

This problem has been occuring in the last few versions of zsh

Output of reporter:

# START zsh saveset
# uname:  AIX ibm 2 3 000227274700
