<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Add missing doc blocks to `revision.php`.
Clarify `@return` values where necessary.
In `wp_delete_post_revision()`, `wp_delete_post()` doesn't return `WP_Error`, so that check can be removed.
`wp_revisions_to_keep()` always returns an `int`, so `wp_revisions_enabled()` can use strict comparison.
