To support code block directives like :exports none we need context - i.e. we
need to have the block and it's results at once and can't just render them
independently.
inside src example blocks lines starting with `\s*,` are escaped - i.e. org
mode will not try to parse them as e.g. a headline. We don't want to render the
escape commata to html so let's take them out - and put them back in before
rendering to org. Doing it this way allows us to render them correctly even
when the input did not include them.

WriteNodesAsString is simple enough to implement but exposing it is helpful in
the implementation of extending writers and we don't aim to keep writer a small
interface so let's expose it.
Being able to very easily get the original [1] Org mode content seems like
something that will come up quite often and is very little code.
[1] it's not really the original content, but rather the pretty printed version
of that - as the semantics don't change it shouldn't matter.
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.
While adding another test case from the goorgeous issues it became clear that
inline markup and html entity replacement were erronously applied to raw text
elements like inline code =foo=, src/example/export blocks, example lines,
etc.
To correctly handle those cases in both org and html exports a new
parseRawInline method had to be added.
Also some misc html export whitespace fixes and stuff
I went through the issues of goorgeous and picked a few that seemed easy enough
to add (and added some fore as todos for later). That helped a lot and showed
some bugs / edge cases that required changes.
- the org writer wrote a lot of eol spaces and just removed it whenever
String() was actually called. That worked until now but did not bode with
rendering an empty headline - by removing ALL eol space we would render "* "
back as just "*" -> not a headline anymore.
- the html writer had some special handling for line spacing inside paragraphs
and list items - with the introduction of more blocks we need that handling
everywhere.
As browsers / html renderers are nice enough to collapse whitespace (and
especially collapse "\s*\n" into " ") we can just write out the newlines and
let the renderer take care of the rest.
