From debate with @bwdmonkey , some ideas:

• work better together: effective diffs, understandable changes
• parse information better: plain-text format line-broken on concept
• simple formatting and normalization of markdown (via default remark stringify)
• unchanged rendering

could also do another read of Semantic Line Breaks (though we dont adhere to it) for ideas
