Don't uniformly colorize content of open block

[mojavelinux]

Description

The open block is often used to group other block-level AsciiDoc content. (It's most frequently used to attach arbitrary block-level content to a list item). As such, the content of the open block should be highlighted as AsciiDoc. Currently, the content of an open block is uniformly colorized (like a literal block) and there is no indication of syntax inside its boundaries. We can still highlight the delimiters (aka fences).

end

Then, run the Bundler command to install it:

 $ bundle install

It's not colorized like a literal block but like a raw code block.

@mojavelinux What do you prefer?

Yes, that's what I meant.

I like solution A. The reason I say that is that an open block is merely a grouping block (like a div, really). So we should only put a lasso around it rather than imply that it is some sort of semantic type via color.

Now, I better understand the meaning of this block
