Also dismissed implementing colgroups for now - had it but didn't like the
added complexity for a very questionable benefit - i've actually never used
that feature of org tables...
- was missing spaces between attributes when rendering to org
- was duplicating attributes when rendering to html - now we join / replace
attributes depending on the name - for now only class & style are appended
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.
