ConciseView mangles multiline errors thrown from scripts, but not from binary cmdlets

[MatejKafka]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

echo 'throw "test`ntest"' >script.ps1
.\script.ps1

If a script throws a multi-line error using throw, all newlines are replaced with spaces. This does not happen with binary cmdlets and advanced functions using $PSCmdlet.ThrowTerminatingError(). Structured error messages are much harder to read this way. Example from one of my scripts:

throw ("Pog cannot create symbolic links, which are currently necessary for correct functionality.`n" +`
        "To allow creating symbolic links, do any of the following and re-run '$PSCommandPath':`n" +`
        "  1) Enable Developer Mode. (Settings -> Update & Security -> For developers -> Developer Mode)`n" +`
        "  2) Allow your user account to create symbolic links using Group Policy.`n" +`
        "     (Windows Settings -> Security Settings -> Local Policies -> User Rights Assignment -> Create symbolic links)`n" +`
        "  3) Always run Pog as administrator.")
