Adjacent challenge block quotes are parsed as one

[zkamvar]

For example, in episode 3 of the git lesson there are two challenge blocks adjacent to each other: http://swcarpentry.github.io/git-novice/03-create/index.html, but the get_blocks() function is only returning one continuous block quote.

Note that I can get around this with the graph representation or maybe inserting a break after the tag, but it's still annoying nonetheless.
