Markdown generation is adding extra '\' character when encountering <br>

[hawkerm]

Given this HTML:

<div style="font-size:12pt;;"><p style="font-size:10.5pt;margin:0;">Some <strong>initial </strong>text.</p><p style="font-size:10.5pt;margin:0;"><br></p></div>

Calling Html.ToMarkdown is returning:

Some **initial** text.

\

With an extra non-sensical '\' at the end.

@erdomke could it possible be this code branch behaving unexpectedly?

BracketPipe/src/BracketPipe/Parser/Text/MarkdownWriter.cs

Lines 384 to 388 in cba73e5

	case PreserveState.None:
	_writer.Write('\\');
	_writer.Write(_settings.NewLineChars);
	WritePrefix();
	break;

Any thoughts?
