I've encountered what may be a bug or few. It seems that blockquotes can't become less-nested, at least not easily. Take the following:
one deep
two deep
three deep two deep one deep
The code for that is:
> one deep
>> two deep
>>> three deep
>> two deep
> one deep
There should be a nice neat nesting up then nesting down, but it all gets appended to three deep instead.
I discovered this during trying to place this post: Spatial analysis? Two layers? (where one of the sub-nests works, but the other didn't)
My follow on question would be - Even assuming block-quotes work, are they they best way to style that sort of thing? Because they don't seem to respect single return characters. I.e.:
>one
>two
>three
is actually three separate lines (look at the "edit") and this line is actually a fourth line that doesn't have any > arrows at all, yet has still been subsumed.
...yields:
