In a markdown file, the trailling two whitespaces is meaningful

[wasphin]

In a markdown file, the trailling two whitespaces are meaningful. So is there an option to skip trimming these two whitespaces.

See syl20bnr/spacemacs#6510

What's the significance of two trailing white spaces in markdown?

@lewang. newline.

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

Is it only two spaces? Does 3 spaces just have no valid meaning?

It seems like ws-butler should just not be enabled for this mode.

@lewang, the docs said that 2 or 2+(2, 3, 4, ...) spaces are all meaningful.
Yes, though less willing to disable it.

Can you try #24 ? If it fixes the issue I will cut a release with this change soon.

Seems not work, some instructions is needed.
Not that familiar with Emacs. I use Spacemacs to manage packages, the ws-butler version is 20150126.759.
Here is what I do:

1. replace the ws-butler.el file;
2. run emacs --batch --eval '(byte-compile-file "ws-butler.el")'

[wasphin]

@lewang, it works. It seems Spacemacs only use ws-butler in changed mode.

It works if I set dotspacemacs-whitespace-cleanup to changed.
