Indent c style multiline comments correctly when they switch indentation.

[belav]

When a file is using the /* style comment and starts with tabs or 2 spaces for indentation, then the comments do not get indented correctly.

See https://github.com/belav/csharpier/releases/tag/comments for some possible code.

  public void Method()
  {
    /*  multiline 
     *  multiline
     */
    var variable = true;
  }

// should be

    public void Method()
    {
        /*  multiline 
         *  multiline
         */
        var variable = true;
    }

Commented out code should retain its formatting.

/*
public class CommentedCodeShouldKeepFormatting
{
    void MethodName() { }
}
*/
