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
including org files is more complex - e.g. footnotes need to be namespaced to
their source file. org does this by prefixing each included files footnotes
with a number - but even that is not enough as it doesn't guarantee
uniqueness.
As I don't have a usecase for it, I'll avoid the additional complexity for
now.
until now buffersettings were always appended using \n which means the first
value would already be written as "\nVALUE". Not anymore.
Also we finally add an option to parse just the front matter. Still not
efficient as we tokenize the whole org file but i don't think saving a few
milliseconds would be worth making the code uglier.
