Although it is not the recommended approach, sourcing a completion
script is the simplest way to get people to try using shell completion.
Not allowing it for zsh has turned out to complicate shell completion
adoption. Further, many tools modify the zsh script to allow sourcing.
This commit allows sourcing of the zsh completion script.

PowerShell 7.2 has changed the way arguments are passed to executables.
This was originally an experimental feature in 7.2, but as of 7.3 it is
built-in. A simple "" is now sufficient for passing empty arguments, no
back-tick escaping is required.

Fixes#1816
Previously, arguments with a dash as the second character (e.g., 1-ff00:0:1)
were detected as a flag by mistake. This resulted in auto completion misbehaving
if such an argument was last in the argument list during invocation.
When the command searches args to find the arg matching a
particular subcommand name, it needs to ignore flag values,
as it is possible that the value for a flag might match
the name of the sub command.
This change improves argsMinusFirstX() to ignore flag values
when it searches for the X to exclude from the result.
Fixes#1831
By moving the check for help group existence to "ExecuteC()" we no
longer need groups to be added before AddCommand() is called. This
provides more flexibility to developers and works better with the use
of "init()" for command creation.

* use arithmetic evaluation in numeric context
* remove unnecessary $ from array index variables
* [[ ]] over [ ], == over =, remove unnecessary quoting
* use ${foo-} rather than ${foo:-} in emptiness check
The result of the expansion is null no matter if the variable is unset
or null in both cases; the former form is arguably easier on the eye.
* remove unnecessary trailing linefeed removal
No longer needed as of f464d6c82e, saves
a subshell.
* use herestring in activehelp extraction
Herestrings read cleaner than process substitutions, and work in posix
mode (but we do and will have some process substitutions so this doesn't
matter much). Both approaches may end up using temporary files.
* Add tests for grouping commands
* Adds Additional Command section in help

Fixes#1786
The --help, -h, --version and -v flags are normally added when the
`execute()` function is called on a command. When doing completion
we don't call `execute()` so we need to add these flags explicitly to
the command being completed.
Also, we disable all further completions if the 'help' or 'version'
flags are present on the command-line.

When a user has an alias in powershell, she will need to register that
alias for completion. To make that possible, we store the completion
logic into a scriptblock variable which can easily be accessed by the
user to register aliases.
For example, if the user defines an alias for `helm`:
PS> sal h helm
she will need to register the alias like so:
PS> Register-ArgumentCompleter -CommandName 'h' -ScriptBlock $__helmCompleterBlock

This method is the OnInitialize counterpart. Like OnInitialize which allows
loading the configuration before each command is executed, OnFinalize allows
saving the configuration after each command has been executed.
Add a global `EnableCaseInsensitive` variable to allow
case-insensitive command names.
The variable supports commands names and aliases globally.
