Markdig 0.37.0

Example link: https://github.com/xoofx/markdig_
Result: <a href="https://github.com/xoofx/markdig">https://github.com/xoofx/markdig</a>_

var pipeline = new MarkdownPipelineBuilder().UseAdvancedExtensions().Build();
var result = Markdown.ToHtml("https://github.com/xoofx/markdig_", pipeline);

Console.WriteLine(result); //-> <p><a href="https://github.com/xoofx/markdig">https://github.com/xoofx/markdig</a>_</p>

Github has same behaviour, so it's not a bug I guess?

This is intentional - some trailing punctuation characters are trimmed from autolinks.
See https://github.github.com/gfm/#extended-autolink-path-validation

I'd suggest enclosing potentially problematic links in brackets manually <https://github.com/xoofx/markdig_>
