Subject: [PATCH] Hide trailing white space warning for markdown (#28)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In the markdown syntax, it’s actually valid to have trailing spaces (it
creates a line break).

Quoting https://en.wikipedia.org/wiki/Markdown
> Two spaces at the end of a line
> produce a line break.
