zsh: make color_map and attr_map more robust

Browse source 
zsh allows to defile "global aliases" which may appear anywhere on the
command line. The most prominent example is:

  alias -g 'L'=" | less "

This allows command lines such as "bzr log L".

In order to avoid such global aliases to be expanded in this
user-sourced utility file, the key need to be quoted.
