PSUseConsistentWhitespace - False validation in switch statements

Before submitting a bug report:

• Make sure you are able to repro it on the latest released version
• Perform a quick search for existing issues to check if this bug has already been reported

Steps to reproduce

1. Create script with following contents:

$TargetLogSize = 64
switch ($TargetLogSize) {
    { $_ -le 64 } { 64 }
    { $_ -ge 64 -and $_ -lt 256 } { 256 }
    { $_ -ge 256 -and $_ -lt 1024 } { 512 }
    { $_ -ge 1024 -and $_ -lt 4096 } { 1024 }
    { $_ -ge 4096 -and $_ -lt 8192 } { 2048 }
    { $_ -ge 8192 -and $_ -lt 16384 } { 4096 }
    { $_ -ge 16384 } { 8192 }
}

1. Execute following settings:

$settings = @{
    IncludeRules = @(
        'PSUseConsistentWhitespace',
    )
    Rules        = @{
        PSUseConsistentWhitespace  = @{
            Enable          = $true
            CheckInnerBrace = $true
            CheckOpenBrace  = $true
            CheckOpenParen  = $true
            CheckOperator   = $false
            CheckPipe       = $true
            CheckSeparator  = $true
        }
    }
}
Invoke-ScriptAnalyzer -Path C:\temp\test.script.ps1 -Severity Warning -Settings $settings

Expected behavior

No warnings to be returned

Actual behavior

Receive warnings on space before an open brace.

まず、PSUseConsistentWhitespace ルールと提供された設定を使用して switch ステートメントの例を再現します。次に、switch 句に対するそのルールの空白検証を追跡し、報告されていた誤った警告が表示されなくなった一方で、実際のスペースに関する警告は引き続き検出可能であることを確認します。
