* We have now dedicated run over the inline marks for them.
* We check more throughly whether it really looks as an URL or e-mail
address. The old implementation recognized even heavily broken ones.
* This allows us to be much more careful in order not to cross already
resolved marks.
* Share substantial parts of the code between all three types of the
permissive autolinks (URL, WWW, e-mail).
* Merge their tests into one file, spec-permissive-autolinks.txt.
* Add one pathological case which triggered quadratic behavior in the
old implementation.
With a new flag MD_FLAG_WIKILINKS, recoginize wiki-style links
as [[foo]] and [[foo|bar]].
Update also the HTML renderer accordingly, to output a custom
HTML tag <x-wikilink> when seeing it.
* scipts/build_*_map.py: Implement helper pythonic scripts used to
generate some Unicode search maps and data for helper Unicode
functions used in MD4C.
This should simplify updating to future Unicode versions.
* md_get_unicode_fold_info: Use data generated by the scripts.
* md_is_unicode_whitespace__: Ditto.
* md_is_unicode_punct__: Ditto.
It is now much more compatible to Cmark-gfm.
With the flag MD_FLAG_PERMISSIVEWWWAUTOLINKS, we now also support the
WWW autolinks (when the http: scheme is omitted).
With MD_FLAG_PERMISSIVEURLAUTOLINKS, we treat not overly complicated URLs
as autolinks even without '<' and '>'.
With MD_FLAG_PERMISSIVEEMAILAUTOLINKS, we treat not overly complicated
e-mail addresses as autolinks even without '<', '>' and without the
'mailto:' scheme.
Also expanded md2html utility and tests to cover these.
