Feature request: conceal checkboxes

[alok]

Or add an option to do so. I realize that checkboxes like GFM supports are not in Pandoc Markdown, but they're damned useful.

Now that pandoc officially supports checkboxes, I was wondering if this feature could be considered.

[alerque]

Yes @alok this would be considered. If anybody wants to put together the rules and submit PR I'd be happy to review and merge it.
