- Remove unused footnote section title option
- Move away from maintaining a list of footnotes in the document (only needed
for html export, potential maintainance overhead when modifying the document)
and rather only build it on export when required.
- HTML export: Rename all footnotes to numbers (so we can support anonymous
footnote references by assigning them a number) and export footnotes in order
of reference, not definition. The implementation of this makes it natural to
also stop exporting unused footnote definitions so we do that as well.
Hugo has some hardcoded checks that have to be fulfilled in its Table of
Contents extraction workflow (helpers/content ExtractTOC). It's easier this
way...
- Footnotes separator rather than headline to get around i18n
- Warn on footnote redefinition
- Do not export footnote definitions at point of definition, only in the
footnote section.
- Do not automatically exclude Footnotes section to get around possibly hiding
other content of such a section - and i18n.
The user has the choice of explicitly hiding the section via a :noexport:
tag.
and some other refactoring
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...
... hopefully correctly
This will hopefully improve ease of developing (more granular test results) and
prepares us for adding example org->html renders for gh-pages
