Message:

Apply order to each passed value for orderby in WP_Query:

• Since orderby in WP_Query can accept space-delimited sets, yet only one order value: when multiple values are passed (and DESC is the order), the default sort order ASC is being applied to all values before the last in the set.
• There is a unit test that sporadically fails since 3.6 in tests/post/revision due to multiple posts having the same post_date from being added so rapidly
• When ordering revisions in wp_get_post_revisions(), order by post_date ID
• Change the order value in wp_get_post_revisions() to ASC. This will produce SQL like: ORDER BY $wpdb->posts.post_date ASC, $wpdb->posts.ID ASC. Previously, this would have produced SQL like: ORDER BY $wpdb->posts.post_date DESC, and with the addition of ID: ORDER BY $wpdb->posts.post_date ASC, $wpdb->posts.ID DESC. Clearly, wrong. The original SQL produced: ORDER BY $wpdb->posts.post_date DESC. As such, return the reversions in reverse order using array_reverse(). Not doing so would break "Preview Changes."
• Add unit tests to assert that all of this works.
• All existing unit tests pass with the change to ordering multiple orderbys in WP_Query.
• In the future, we should support independent order for each orderby, see #17065.

Props SergeyBiryukov, wonderboymusic.
