[Dlang-internal] Potential changes to DDoc

[Walter Bright]

I agree completely with your reasoning that what we are doing should not be 
called "supporting Markdown". The farthest we should go is saying "inspired by 
Markdown." I also agree that we should fully document how this will work in Ddoc 
rather than referring to the Markdown spec.

Please be careful in copying any text, tests, or examples from the Markdown spec 
to ensure we fully comply with any licensing terms on their site. It may be more 
practical to just do our own tests and document how ours works in our own words. 
Frankly, I'd prefer doing the latter anyway so the D spec is 100% our work.
