Two spaces at end of line doesn't work as expected.

I expected that two spaces at the end of a line indicates that a line break should be inserted, but at the moment this is not the case.

Gruber explicitly writes https://daringfireball.net/projects/markdown/syntax#p

When you do want to insert a <br /> break tag using Markdown, you end a line with two or more spaces, then type return.

It might be that " \r\n" is not triggering a new line, but " \n" is not.
