- drawer entries without value were printed as FOO rather than :FOO:
- account for differences between raw & non-raw block:
raw blocks are not wrapped in a further element, just raw text & line breaks:
-> the first line has to be indented manually
non raw blocks do not end in a linebreak newline -> the END_BLOCK line has to
be indented (rather they end with a manual newline from another element)
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.
Until now we expected the .org file to print back to itself - we can't do that
when the input is not pretty printed already - with the introduction of blocks
with unindented content that will be the case.
