A long time issue with Markdown was that there was no standardization (and when
I used Pillar's MD export ~2 years ago it didn't work well).
However CommonMark ( http://spec.commonmark.org/0.28/ ) has become the de-facto
standard, so it would make sense to support it bidirectionally with Pillar.

Well, technically it is just a CommonMark, as I am not using any github
(Github uses CommonMarks and adds just couple small extensions.)
