Ah, i have none of those set though, and i don't use a zshaddhistory
hook... This is a zsh -f session:

% cat /tmp/test
HISTFILE=/tmp/test
HISTSIZE=50
SAVEHIST=50
setopt incappendhist
setopt incappendhistory
cat /tmp/test
setopt extendedhistory
: 1319731616:0;cat /tmp/test
: 1319731618:0;sleep 5
: 1319731624:0;cat /tmp/test

% history -dD
    1  18:06  0:00  HISTFILE=/tmp/test
    2  18:06  0:00  HISTSIZE=50
    3  18:06  0:00  SAVEHIST=50
    4  18:06  0:00  setopt incappendhist
    5  18:06  0:00  setopt incappendhistory
    6  18:06  0:00  cat /tmp/test
    7  18:06  0:00  setopt extendedhistory
    8  18:06  0:00  cat /tmp/test
    9  18:06  0:05  sleep 5
   10  18:07  0:00  cat /tmp/test

At first i thought maybe it's one of my local patches, but i get the
same result on a remote host running 4.3.10.
