<#
.SYNOPSIS
    Git Clone extended input
.DESCRIPTION
    Extends the input for git clone.

    By default, if --progress is not found, it will be added to any git clone.
.EXAMPLE
    git clone https://github.com/MDN/content.git # This is a big repo. Progress bars will be very welcome.
.EXAMPLE
    # If we don't check things out, cloning is faster.
    git clone https://github.com/PowerShell/PowerShell -NoCheckout
    # (of course, that's because we're not copying files, just history)
.EXAMPLE
    # We can also clone more quickly by only picking a certain number of commits
    git clone https://github.com/Microsoft/vscode.git -Depth 1
    # (of course, this will make the history lie to you,
    # by saying everything was changed whenever anything was changed)
