• OS Version: Windows_NT ia32 10.0.14393
• Extensions: the listing length exceeds browsers' URL characters limit

Steps to Reproduce:

1. PowerShell
   Settings.json:
   "editor.formatOnSave": true,
   "editor.formatOnType": true,

Desired Formatting:

Get-Process |  ForEach-Object `
   -Begin {
      $Count = 0
   } `
   -Process {
      $Count++
   } `
   -End {
      $Count
   }

Bug Formatting

Get-Process |  ForEach-Object `
   -Begin {
    $Count = 0
} `
    -Process {
    $Count++
} `
    -End {
    $Count
}

Reproduces without extensions: Yes/No

@aeschli This seems to be caused by the new default of editor.autoIndent: true. I've been getting a few reports of code being improperly formatted on paste with this setting turned on. Is there an easy way to test my indentation regexes to make sure they work correctly with this new default behavior?

Seeing similar behavior auto-formatting/indenting this as:

             $b = Invoke-NullCoalescing `
-                { dbg 'Trying symbolic-ref' $sw; git --no-optional-locks symbolic-ref HEAD -q 2>$null } `
-                { '({0})' -f (Invoke-NullCoalescing `
+            { dbg 'Trying symbolic-ref' $sw; git --no-optional-locks symbolic-ref HEAD -q 2>$null } `
+            { '({0})' -f (Invoke-NullCoalescing `
                     {
                         dbg 'Trying describe' $sw

I would expect any escaped newline to be indented relative to the first line of the expression.

One more case. I want it to be like this:

Microsoft.PowerShell.PSResourceGet\Get-InstalledPSResource -Path $Script:ModulesPath | `
    Where-Object -FilterScript {
        $_.'Type' -eq 'Module' -and
        $_.'Repository' -eq 'PSGallery' -and
        -not ($IncludePreReleaseVersions -and $_.'IsPrerelease')
    } | ForEach-Object -Process {
        Add-Member -InputObject $_ -MemberType 'AliasProperty' -Name 'Path' -Value 'InstalledLocation' -PassThru
    } | Group-Object -Property 'Name' | Select-Object -Property 'Name',@{'Name'='Versions';'Expression'='Group'}

Auto indent does this:

Microsoft.PowerShell.PSResourceGet\Get-InstalledPSResource -Path $Script:ModulesPath | `
    Where-Object -FilterScript {
    $_.'Type' -eq 'Module' -and
    $_.'Repository' -eq 'PSGallery' -and
    -not ($IncludePreReleaseVersions -and $_.'IsPrerelease')
} | ForEach-Object -Process {
    Add-Member -InputObject $_ -MemberType 'AliasProperty' -Name 'Path' -Value 'InstalledLocation' -PassThru
} | Group-Object -Property 'Name' | Select-Object -Property 'Name',@{'Name'='Versions';'Expression'='Group'}
