Hi,

Is there an option that allows consecutive cd or pushd
 commands to modify the top entry in the cd stack and
command history, instead of adding to it?

e.g.
---------------------------
LE-XP% setopt autopushd
LE-XP% cd temp
LE-XP% cd temp2
LE-XP% dirs
~/temp/temp2 ~/temp ~
LE-XP% history
    1  setopt autopushd
    2  cd temp
    3  cd temp2
    4  dirs
LE-XP%
---------------------------

becomes

---------------------------
LE-XP% setopt autopushd
LE-XP% cd temp
LE-XP% cd temp2
LE-XP% dirs
~/temp/temp2 ~
LE-XP% history
    1  setopt autopushd
    2  cd temp/temp2
    4  dirs
LE-XP%
---------------------------

Thanks
-lw
