history_ignore_dups does not work

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Uncomment hist_ignore_dups in 111.environment.options.zsh
2.
3.

What is the expected output? What do you see instead?

Duplicates in history should be, but are not, ignored. Furthermore, this output 
is seen when I open a new shell (via ssh in this case)

Besides the error message it looks like the shell executes the 111-file three 
times. That can't be right, can it?

What version of the product are you using? On what operating system?

The header of the 111-file:

# File:  $ZDOT/zshrc.d/environment.options.zsh
# sourced from /etc/zshrc
# Version: 2.0.0

on Snow Leopard.

Please provide any additional information below.

Ok, I have figured the problem. The layout in 111_environment.options.zsh:186 
is not ideal. You can't just uncomment lines you want to apply, you have to 
preprend them with setopt, e.g.,

# some option
# hist_ignore_dups
# another option

would become
# some option
setopt hist_ignore_dups
# another option

Actually, a smarter design of the file would be without \ (to ignore line 
breaks) and prepend all options with setopt and then comment the options one is 
not interested in.
