Christoph Bergmeister (@bergmeister) Thanks for fixing issue.

In very rare cases, I think the following codes may still produce unexpected results.

> Invoke-Formatter '?et-Content $file'
Get-Content $file

> Invoke-Formatter 'Get-* $file'
Get-AppPackage $file

How about we consider using [WildcardPattern]::Escape() in the Get-Command ?
