- Add ~/.zshrc
+ Configure on how the `history` works
+ Enable nicer `cd` and globbing behavior
+ Enable tab completion, and make them feel nicer
+ Enable VI mode and add some VI-like key bindings
- Add ~/.zlogout clearing the screen
- Add ~/.config/zsh/.zshrc and make it dispatch to ~/.zshrc
to make `zsh` use the same configuration even on more
recent Debian/Ubuntu machines that do not look for
~/.zshrc any more
- Ensure ~/.local/state/zsh/ exists
