Orbited plugin may not work at all anymore, I had no means to try it.
But there's a check whether 'LACONICA' is defined there, which is a
very unlikely thing in the future. So far only tests and scripts have
been migrated consistently, though.
URLs with paths followed by a double-quote character are incorrectly including the quote in the URL. The double-quote character is in fact not a legal URL char and must be URL-escaped; more importantly it just causes oddities when you quote a message ending in a URL -- such as when using the redent-button experimental feature.
After removing 103 false positives, this leaves 4 actually broken tests, showing two failure modes for mail links:
* 'mail without mailto' formatting shortcut in common_linkify didn't get the 'title' attribute added with the other URLs
* links including mailto: protocol are being incorrectly expanded to http: protocol in the long URL
Canon urls that have a protocol followed by a host (and no path) automatcally get a trailing slash by the canon function - make the unit test match that
