Change OS X to macOS in the README file in line with apples rebranding
of the operating system.

Change OS X to macOS in the read me file in line with apples rebranding
of the operating system.

Fixes #5520.

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

Fixes #4834

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.

Based on #5488.

Also, force the use of Bourne-style shell syntax with `dircolors -b`.

GNU coreutils ship a color setup command by default which can be used to
set a good default color theme for ls:

* 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.

Adds commits from #3007 and #5158.

Closes #3007
Closes #5158

Fixes #5246
