Changes between Version 2 and Version 3 of Ticket #39321, comment 2

v2	v3
3	3	I was programmatically importing and updating data when I noticed this. With this part:
4	4	`Your change would make this worse, since the structure of the URL would be different for authorless revisions: example.com/authorname/postname vs example.com/postname. Perhaps revisions should always have permalinks of the form ?p=123, as is the case with draft, pending, auto-draft, and future.`
5		Not sure that's actually true, because in this situation `$author = $authordata->user_nicename;` never actually worked ~~since `post_author=0`, `$authordata` is not an object and `$authordata->user_nicename;` is just `NULL`, so it would actually just remain~~ the same but with the added bonus of not throwing a PHP Notice :-)

7	7	I like the idea of reverting to non-pretty permalinks for revisions as I think this is the safest course of action and follows suit with draft, pending, auto-draft statuses.
