error WHITESPACE is an invalid report

I used this: `dotnet format --verify-no-changes` on my project. It reported this:

> C:\Source\...\Handlers\HttpRequestHandler.cs(14,30): error WHITESPACE: Korrigieren Sie die Leerraumformatierung. Ersetzen Sie 4 Zeichen durch „\r\n\r\n“. [C:\Source\...\MyProject.csproj]

The relevant code looks like this:

```cs
using Microsoft.Extensions.FileProviders;
using Microsoft.Extensions.Logging;

namespace MyProject.Handlers;

///
/// Registers HTTP path routes and provides handlers for each route.
///
internal class HttpRequestHandler : RoutingRequestHandler
{
```

The given line and column are at the end of the `namespace` line (namespace itself edited, column may not match in this example).

What?!

I shall replace 4 (non-existing) characters (probably just the existing 2 line breaks which are `\r\n\r\n`) with – `\r\n\r\n`. That is no change at all. Why is this reported? And the tool output is full of these. Looks severely broken, can't use this thing at all.

I learned from a dotnet blog post that I could use this command in my agent instructions, but I'd better not do that if I want results.

Reproduce the report with `dotnet format --verify-no-changes` using the shown namespace and blank lines, then inspect how the WHITESPACE diagnostic reports its line, column, and replacement text. Done means valid unchanged whitespace no longer produces misleading WHITESPACE errors or replacement instructions.
