find-file pointlessly suggests recovery of identical auto save version

[Dan Davison]

find-file tells me to "consider M-x recover-this-file" even when the
contents of the auto save file are identical to the file being
opened. Would it not make sense to add an extra condition to the test
below (from after-find-file in files.el) that checks whether the backup
data is actually different? (for reasonably-sized files at least?)

Thanks,
Dan
