"Format Document" removes stream redirection operators when "powershell.codeFormatting.whitespaceBetweenParameters": true, changing semantics of code

[mmotejlek]

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

After using the "Format Document" command when "powershell.codeFormatting.whitespaceBetweenParameters": true is set, stream redirection operators like 2>&1 from statements like Get-Content "a.txt" 2>&1 > "b.txt" are removed, resulting in Get-Content "a.txt" > "b.txt", which changes what the code does. That should not happen after autoformatting code.

Hi, this is/was a bug in PSScriptAnalyzer: PowerShell/PSScriptAnalyzer#2000 the fix has been merged but we're still pending a release (which we'll then need to pull in here) so it'll be fixed soon enough!
