A new command line option `--syntax-highlighting` is provided; it takes
the values `none`, `default`, `idiomatic`, a style name, or a path to a
theme file. It replaces the `--no-highlighting`, `--highlighting-style`,
and `--listings` options.
The `writerListings` and `writerHighlightStyle` fields of the
`WriterOptions` type are replaced with `writerHighlightStyle`.
Closes: #10525
- The `PANDOC_STATE` is no longer a userdata object, but a table that
behaves like the old object.
- Log messages in `PANDOC_STATE.log` are now in temporal order.
The state is an internal value and should be treated as such. The
`PANDOC_STATE` global is merely a copy; unsetting the global no longer
breaks the Lua engine.
Rationale: we need this splitting level now not just in
EPUB but in chunked HTML.
`--epub-chapter-level` will still function as a deprecated
synonynm. `epub-chapter-level` will also continue to work in
defaults files, ande `epub_chapter_level` will still work for
Lua marshalling.
[API changes]
