GFM: Line break using a backslash about markdown

[cebe]

The GithubMarkdown class doesn't support those. Only double-space breaks are allowed. It would be really nice if that feature would be added.

seems it is a newly added feature.

• \ is a marker for the parseEscape function, so extending it should allow implementing this:

markdown/Parser.php

Lines 368 to 378 in eeb1bf6

	/**
	* Parses escaped special characters.
	* @marker \
	*/
	protected function parseEscape($text)
	{
	if (isset($text[1]) && in_array($text[1], $this->escapeCharacters)) {
	return [['text', $text[1]], 2];
	}
	return [['text', $text[0]], 1];
	}

have not checked it in detail though.
