 I'm in a situation where I need to preserve the original post revision and
 prevent it from being deleted once a post is past the max number of
 revisions for the site. This is more difficult than it seemed, because
 WordPress doesn't have many filters around the revisions delete process.

 If we add a new filter to the result of `wp_get_post_revisions` in
 [https://github.com/WordPress/WordPress/blob/master/wp-
 includes/revision.php#L201 revision.php], then I'd be able to slice out
 the revision that I don't want to get deleted and instead delete the next-
 oldest one.
