Enabling Post Revision causes Diff.php error output.

Hi all,

This could be a case of me using an old tag or something to do with my server.

However, I’ve enabled Post revision using the following code:
define('WP_POST_REVISIONS', true );

When I go into the history of the Post (or Page), I get the following errors:

Deprecated: Assigning the return value of new by reference is deprecated in /wp-includes/Text/Diff.php on line 380

Deprecated: Assigning the return value of new by reference is deprecated in /wp-includes/Text/Diff.php on line 402

I’ve read somewhere that putting this into the code will remove the server from reporting these errors:
error_reporting(E_ALL & ~E_DEPRECATED);

However I just want to make sure that is correct, also Post revision appears to work even with the above error output.
