/**
  * Automatically review an revision and add a log entry in the review log.
  *
  * This is called during edit operations after the new revision is added
  * and the page tables updated, but before LinksUpdate is called.
  *
  * $auto is here for revisions checked off to be reviewed. Auto-review
  * triggers on edit, but we don't want those to count as just automatic.
  * This also makes it so the user's name shows up in the page history.
  *
  * If $flags is given, then they will be the review tags. If not, the one
  * from the stable version will be used or minimal tags if that's not possible.
  * If no appropriate tags can be found, then the review will abort.
