Recent Changes is incompatible with Diff Module 2.x

If I use recent_changes.module 5.x-1.2 and diff.module 5.x-2.1, I get a blank page when viewing the RSS feed, and the following in the Apache error logs:

PHP Fatal error:  Call to undefined function _diff_table_body() in .../sites/all/modules/recent_changes/recent_changes.module on line 596

_diff_table_body() was refactored in diff.module 5.x-2.x.

Here's a patch that solves the problem for me:
