I'd like anyone to be able to view the content of revision.php -- I'd like them to be able to view revisions and make comparisons. I'd like it to be the same as for a logged in user except they shouldn't be able to restore old revisions. It looks like anyone who is logged in can access this functionality.
Any ideas on how to change it so logging in is not required?
I've also noticed that the revision list is different for an admin user versus and subscriber. In particular, it seems the subscriber can always see just the last two revisions while the admins can see all revisions.
Ideally I'd like to show all the revisions. Thanks in advance for your thoughts!
