@sam, help required. I need info, can links from real world end with _, ~, - or +.
http://example.com/?sdf,wer- and so on.
That’s important to know before markdown-it’s linkifier rewrite. Could you grep some huge postings databases for such cases and let me know if anything found or not found? Probably, those links were posted as <...> for workaround. So, regexp pattern for db scan will be something like /<http.+[+~_-]>/g (not tested)
I have no access to such big volume of markdown texts to reach acceptable confidence. May be you could help, or know anyone who could help?
