Revision meta box is hidden when one revision

[ecairol]

When editing a post, if there's only 1 revision associated with the post, the meta box will be hidden. The cause of this is the condition being > instead of >=

On file: wp-admin/includes/meta-boxes.php

<?php
// We should aim to show the revisions meta box only when there are revisions.
if ( count( $revisions ) > 1 ) {

If the aim is to show the box when there are revisions, even one, then the condition should have been $revisions >= 1.

If you set your wp-config to store only 1 single revision per post, the meta-box won't display.

I read the first step is opening this ticket, however I'm more than happy to open a PR with a fix.
