* add docker-compose down alias

* rename `docker-compose down` alias to `dcdn`

Closes #5568

Source:
https://github.com/docker/docker/commit/c9fdf9abf8d6443598808809b900d96e04adfcb1

Removing one "apt-get autoremove" alias because it is duplicated.

The m4a file format can be opened in the command line with mplayer

This allows for the user to combine the jump command with something else. In my example cd and jump are now combined like this:

```bash
jumpcd() {
        jump $1 > /dev/null || cd $1
}
alias cd="jumpcd"
```

The command `compdef command=git` returns an error in some cases, the
appropriate command is `compdef _git command`.

Fixes #5442

Latest version: February 17, 2016 - dd81201

Also:

- Changes `globes` (which doesn't exist) to `glob expressions`.

- Delete the `trigger autocompletion to your current aliases` use case, since that's not
  really implemented.

* cp plugin: change cpv to function so that completion works

* cp plugin: show numbers in units of 1024 (K,M,G,T)

Use `-h` level (3): output numbers in units of 1024.
See the manpage of rsync for more information.

* cp plugin: add a README file

* cp plugin: recurse directories

* cp plugin: remove `--` to separate files from options

This has some undesired effects, like having `cpv --help` be a file
not found error.

Use `--` yourself if you need it (which you generally don't):

```zsh
cpv -- -some-file-with-hyphens.txt /tmp
```

Added this same info to the README.

The current list of directories to search for autoenv on misses the default location on Ubuntu systems if you just do a normal `pip install autoenv` - [it will place](https://github.com/kennethreitz/autoenv/blob/master/setup.py#L16) `activate.sh` in `/usr/local/bin` unless you manually override the `--prefix` or something.

The `/usr/local/opt/autoenv` is fine for macOS/homebrew installations but it would be nice not to have to manually patch on Linux :)

When making a WIP commit, we generally just want to save the state of the
current branch temporarily, maybe because we want to push our work for backup
purposes, or change branch to work on something else. Therefore, it's generally
undesirable to run Git hooks, which might do things like run linters, because
we probably don't care if our WIP has lint errors.

`${var:t:h}` uses:

- `${var:t}` which acts as `basename`.

- `${var:r}` which removes the extension.
