Support tab completion in zsh

[MartinMartimeo]

No tab completion seems to be available.

Is that something we can include in the binary or does it has to be provided separately?

edit: If we include this, maybe should also include the completion for bash?

There are different approaches how to implement tab completion in shell

You can provide a source file to be included that calls complete (that works for zsh and bash) and handle the tab completion information. There is a tutorial here: http://www.tldp.org/LDP/abs/html/tabexpansion.html. It has the advanges that when providing pkictl via a ppa we also can just drop in the file to /etc/bash_completion.d/

Superior to that you can directly contribute to the zsh repository and provide a tab completion script (I find them somehow easier than the 'old' bash completion functions).
