Dear Grml Maintainers and Zsh-lovers,  ;)

you are known to take great care to not clutter environment, when using your
/etc/zsh/zshrc as base.

I figured non the less some used variables has fallen through.
In particular this example cause real bugs:

<<<<< >8 <<<<< >8 <<<<< >8 <<<<< >8 <<<<< >8 <<<<<
# make sure our environment is clean regarding colors
for color in BLUE RED GREEN CYAN YELLOW MAGENTA WHITE ; unset $color
<<<<< >8 <<<<< >8 <<<<< >8 <<<<< >8 <<<<< >8 <<<<<

here the var color is defined, which is expected by other scripts and functions
to be an array.

Attached is a patch which fixes this and some more.

I hope i didn't break anything. A 4 eyes reviewing can't hurt though.

Thanks!

bye Thilo
