Support blocks with unindented content

list items only contain content that is indented to their respective
level. Except when that content is inside a block. To allow for this we have to
ignore the parentStop when parsing a block and just include everything until
the end of that block.
Can't think of any problems with this right now. Let's see if this comes
back to bite me.
