Blockquotes are awful in markdown, because they're semi optional in continuation lines.
There are three options i've considered:
Option A: Blockquote at start of para, and on every continuation line.
> a
> > b
> c
d
This would parse ( [a] ([b]) [c] ) [d] (quotes in ()s, paras in []s)
Option B: Blockquote at start of Para. No > on continuation lines.
> a
> > b
> c
d
This would parse ( [a] ([b]) [c d] ) (quotes in ()s, paras in []s)
This also works a little like a list does in CommonMark
Option C: CommonMark Rules. Blockquote at start of para, optionally on continuation lines.
> a
> > b
> c
d
This would parse ( [a] ([b c d]) ) (quotes in ()s, paras in []s)
I implemented B, but i'm tempted by A
