windows-linebreaks are considerer non-emptly lines

[tripodsan]

having a markdown with \r\n linebreaks, messup the parser:

# Hello\r\n
\r\n
---\r\n
\r\n
# foo\r\n
\r\n

gives error:

Error: Found ambigous frontmatter fence: No empty line before the block! Make sure your frontmatter blocks contain no empty lines and your horizontal rules have an empty line before AND after them.

That's probably best fixed in https://github.com/remarkjs/remark-frontmatter

I'm mistaken. Since @koraa's refactoring, we don't use remark-frontmatter anymore.
