zsh doesn't load HISTFILE from readonly directory

[JÃrg Sommer <joerg@xxxxxxxxxxxx>]

Hi,

if the directory, containing the history file, is not writeable, zsh
doesn't load the data and I've not history. I've no problem that zsh
can't save the file, but I would like to have the history from the file.

% ls -ld /tmp/aaa
dr-xr-xr-x 2 joerg users 80 13. Jun 15:00 /tmp/aaa

% ls -l /tmp/aaa/.z*
-r-------- 1 joerg users 93 13. Jun 15:00 /tmp/aaa/.zhistfile
-rw-r--r-- 1 joerg users 26 13. Jun 15:00 /tmp/aaa/.zshrc

<1,5029>(ibook):~% cat /tmp/aaa/.zhistfile
: 1276430398:1;ls
: 1276430403:0;cd /tmp
: 1276430407:0;ls
: 1276430427:0;exec $ZSH_NAME -$-

% cat /tmp/aaa/.zshrc
HISTFILE=$HOME/.zhistfile

With this version, you get the history.

% HOME=/tmp/aaa zsh
ibook% fc -l
    1  ls
    2  cd /tmp
    3  ls
    4  exec $ZSH_NAME -$-
ibook% echo $ZSH_VERSION 
4.3.10

But with this version, the history is empty.

% HOME=/tmp/aaa zsh-beta
ibook% fc -l
    1  fc -l
ibook% echo $ZSH_VERSION 
4.3.10-dev-1-cvs0603

Regards, JÃrg
