Description of problem:

The current docker-io package includes shell completion files (bash, zsh and fish) and syntax highlighting files (vim) in the main package itself.

I plan to split the zsh, fish and vim files in their own subpackages (docker-zsh, docker-fish and docker-vim). I'm thinking of keeping bash in the main package itself (I don't think there are (m)any bash-less systems out there)

I had earlier upstreamed the zsh and vim files, but seems like it would be a lot of effort to keep those updated. (fish was upstreamed by someone else)

Please let me know if any comments/objections.
