For zsh.

Which depends on the completion script having a wrapper function
around compgen filling COMPREPLY. However, COMPREPLY will be soon
filled by hand-rolled code to prevent expansion issues with compgen,
and there will be no such wrapper.

There are a couple of constructs supported by Bash but not by zsh,
which we usually try to avoid.
